摘要：

The electrochemical and spectroelectrochemical (UV/VIS/NIR and EPR) properties of a series of complexes of general formula [Pt(bipy)L(2)](n+) (L = Cl- or CN-, n = 0; L = NH3, py, PMe(3) or L(2) = en, n = 2; bipy = 2,2'-bipyridine, py = pyridine, en = ethylenediamine) have been investigated. The complexes undergo a reversible one-electron reduction process at potentials of ca. - 1 V vs. Ag-AgCl. In each case UV/VIS/NIR spectra of the one-electron reduction products were consistent with co-ordinated bipyridyl anion-radical species rather than d(9) metal centres. Electron paramagnetic resonance spectra of the chemically or electrochemically generated 17-electron species, in conjunction with the results of extended-Huckel molecular-orbital calculations, show a significant admixture of metal 5d(yz) and/or 6p(z) orbitals in the singly-occupied molecular orbital. The complex[Pt(bipy)(PMe(3))(2)][BF4](2) has been prepared.
