Book Ground  and Excited state Chemistry of  bis 2 2  bipyridine  2  2 pyridyl pyrazine  Ruthenium II

Download or read book Ground and Excited state Chemistry of bis 2 2 bipyridine 2 2 pyridyl pyrazine Ruthenium II written by Elena Ferloni and published by . 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 Diimine Complexes of Ruthenium ii   Rhenium i  and Iron ii   from Synthesis to DFT Studies

Download or read book Diimine Complexes of Ruthenium ii Rhenium i and Iron ii from Synthesis to DFT Studies written by R. A. Kirgan and published by . This book was released on 2007 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Author's abstract] The chloro and pyridinate derivatives of rhenium(I) tricarbonyl complexes containing the diimine ligands 2,2'-bipyrazine (bpz) and 5,5'-dimethyl-2,2'-bipyrazine (Me2bpz) are discussed. When compared to similar rhenium(I) tricarbonyl complexes of 2,2'-bipyridine (bpy) and 2,2'-bipyrimidine (bpm), the Me2bpz complexes are comparable to bpm derivatives and their properties are intermediate between those of bpy and bpz complexes. Also discussed is the synthesis and properties of two new analogues of ruthenium(II) tris-bipyridine, a monomer and dimer. The complexes contain the ligand 6,6'-(1,2-ethanediyl)bis-2,2'-bipyridine (O-bpy) which contains two bipyridine units bridged in the 6,6' positions by an ethylene group. Crystal structures of the two complexes formulated as [Ru(bpy)(O-bpy)](PF6)2 and [(Ru(bpy)2)2(O-bpy)](PF6)4 reveal structures of lower symmetry than D3 which affects the electronic properties of the complexes as revealed by Density Functional Theory (DFT) and Time Dependent Density Functional Theory (TDDFT) calculations. Iron(II) tris-bipyrazine undergoes dissociation in solution with loss of the three bipyrazine ligands. The rate of the reaction in acetonitrile depends on the concentration of anions present in the solution. The rate is fastest in the presence of Cl- and slowest in the presence of Br-. In a second discussion DFT calculations are used to explore four iron(II) diimine complexes. DFT calculations show the higher energy HOMO (highest occupied molecular orbital) orbitals of the four complexes are metal centered and the lower energy LUMO (lowest unoccupied molecular orbitals) are ligand centered.

Book Synthesis and Spectroscopic Characterisation of Bis bis Bipyridine ruthenium II   3 3  4 4  Tetraiminobiphenyl and Its Redox Products

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).
