This book was released on 2011 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study expands our efforts to make a new class of Pt (II) compounds analogous to cisplatin and its derivatives using sterically hindered ligands. Pt compounds in this series have been synthesized using specially designed pyridine and benzimidazole ligands. These heterocycles, amide functionalized at position 2 with aryl and alkyl pendants, rapidly change their mode of coordination depending on the pH of the medium. These ligands, synthesized using condensation chemistry, also coordinate to Co(II), Ni(H), Cu(lI), and Zn(1I) generally as anionic bis-chelates through the benzimidazole nitrogen and the carbonyl oxygen, creating a four-coordinate complex with the exception of an unusual trigonal bipyramidal Zn(H) complex. I H NMR temperature studies reveal that these ligands interconvert between imide and amide isomers and that electron withdrawing pendants favor amide isomers. Crystal structures of Co(II) and Ni(1I) complexes of N-( I-methylbenzimidazol-2-yl)cyclohexanecarboxamide, for example, show two ligands bind per metal ion when reacted with acetate and nitrate salts. The bischelates of these Ni(1I) complexes also show expansions of their coordination spheres from four to five-coordinate. Furthermore, these Ni(II) bis-chelated complexes possess square planar or distorted 4-coordinate geometries. The synthesis and properties of several new Pt (II) complexes containing these ligands will be presented. A second generation and novel complex class containing metal-binding, linker and recognition domains is reported. Both classes of Pt complexes were obtained using a synthetic methodology which favors the cis isomers. The second generation complex crystallizes in the monoclinic space group P2dn with lattice dimensions a = 17.7393(5) A, b = 11.4632(3) A, c = 19.3959(5) A and ~ = 99.794(3)°. These complexes have been characterized using physical methods that include X-ray crystallography, IH &13C NMR, Mass spectrometry, UV and IR spectroscopies. Complexes similar in structure to cisplatin and carboplatin show varying cytotoxic properties toward different cancer cell lines. Additionally, some of these new Pt complexes show comparable and promising cytotoxicity against prostate cancer cell lines.

This book was released on 2012 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruthenium(II) diimines have been extensively studied for their notable photo physical properties. Of particular interest are compounds with ligands with peripheral base sites, where the metal-to-ligand charge transfer shifts electron density onto the ligand yielding an emissive state of increased in basicity. One well known example of such complexes, (bis(2,2'-bipyridine) (2-3-bis(2-pyridyl) pyrazine) ruthenium(II), [Ru(bpy)2dpp] 2+, has been studied extensively, yet questions remained regarding the sequence of protonation steps at the two peripheral dpp nitrogens in the ground and excited states and the magnitude of the photo-induced change in acid-base properties at each site. In order to reach a deeper understanding of the kinetic and thermodynamic steps involved in its protonation and coordination, a similar complex was synthesized and studied, (bis(2,2'-bipyridine) (2-(2-pyridyl) pyrazine) ruthenium(II), [(bpy)2Ru(pypz)]2+. The alternative ligand is identical in almost every respect to dpp except for the absence of the free pyridyl ring and the fact that it has only one possible protonation site instead of two. The pypz ligand, thus, represents an ideal candidate to elucidate how the pyrazinyl nitrogen on the coordinated dpp would behave if the additional pyridyl ring on dpp was not present. The differences and similarities in the properties of [(bpy)2Ru(pypz)]2+ and [Ru(bpy)2dpp]2+ in the same environment are highlighted here, describing the peculiar behavior of the acid-base sites of each complex upon excitation and their role in protonation reactions and coordination reactions to d10 metals, namely zinc.
Book Synopsis Synthesis and Spectroscopic Characterisation of Bis(bis(Bipyridine)ruthenium(II))-3,3',4,4'-Tetraiminobiphenyl and Its Redox Products by : P. R. Auburn
Download or read book Synthesis and Spectroscopic Characterisation of Bis(bis(Bipyridine)ruthenium(II))-3,3',4,4'-Tetraiminobiphenyl and Its Redox Products written by P. R. Auburn and published by . This book was released on 1990 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tetraiminobiphenyl forms a redox series of binuclear complexes obtained by coordinating the Ru(bpy)2 (bpy = 2, 2 - bipyridine) fragment at each end of the molecule. The ligand is capable of existing in six redox states, and three of these, including a mixed valence species, are characterised as their bis(Ru(bpy)2) complexes. Electrochemical, electron spin resonance and optical data are presented. These are discussed in terms of localisation and delocalisation of the ruthenium to ligand charge transfer states as a function of redox level. The mixed valence species displays an intervalence (ligand to ligand) charge transfer band, and the degree of electronic coupling is shown to be relatively large. There is some evidence that the biphenyl twist angle changes with oxidation state suggesting that these complexes might be useful building blocks for molecular wires and switches. Keywords: Biphenyl, Ruthenium, Redox, Bipyridine. (JES).
Book Synopsis Conducting Metallopolymers with Tridentate Ligands and Coordination Chemistry with Corresponding Model Compounds by : Şeyma Keskin
Download or read book Conducting Metallopolymers with Tridentate Ligands and Coordination Chemistry with Corresponding Model Compounds written by Şeyma Keskin and published by . This book was released on 2013 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conducting polymers that contain metals are remarkable materials, because they have the properties of both organic backbones and metals. Depending on the position of the metal relative to the conjugated backbone, i.e. attached to or directly in the backbone, these two can couple resulting in advancement of the functionality and therefore potential applications of these types of materials. Complexes of tridentate ligands with donor atoms such as phosphorus, nitrogen, and sulfur also have a wide variety of applications. In addition, complexes of tridentate ligands have advantages of stability and control of electron density by variation of donor atoms. Therefore, conjugated polymers with tridentate ligand units will have promise for various applications and advantages in their designs. Complexes of PNP ligand with molybdenum and carbonyl ancillary ligands were synthesized and characterized. Isomerization and conversion reactions between them were investigated as well as the coordination modes. Many types of PNP ligands have been studied in the literature because the hemilabile property of the nitrogen atom promotes some catalytic reactions and gives different coordination geometries. Conducting polymers can be used as redox-active ligands and they can be used to control electron density on the metal attached to them. Synthesis and characterization of a novel polymerizable ligand 3,5-bis-EDOT-N,N-bis[2-diphenylphosphinoethyl]aniline was achieved. Related molybdenum complexes with ancillary ligands as carbonyls were also synthesized and characterized. Monomer complexes and the free ligand were electropolymerized and studied. Tris(bipyridine)ruthenium(II) chloride and analogous complexes have been studied extensively in the literature due to their luminescent and photochemical properties, and excited state lifetimes. Conducting polymers with similar ruthenium groups have been investigated for various applications. Synthesis of four ruthenium complexes with the polymerizable ligand 2,6-Bis[4-[2-(3,4-diethylenedioxy)thiophene]pyrazol-1-yl]pyridine and four different bidentate ligands were reproduced; electropolymerizations of the complexes were achieved; electrochemical, UV-Vis and luminescence studies were performed and discussed. Various complexes of copper, silver, platinum, and palladium with nitrogen and phosphorus donors have been reported for their luminescence behavior as well as their interesting structures. Model complexes of these metals with N,N-bis[2-(diphenylphosphino)ethyl]phenyl-amine (a PNP ligand) have been synthesized and characterized. Absorption and luminescence behaviors as well as the coordination modes were investigated.
