Abstract

© 2015 Pleiades Publishing, Ltd.Binuclear [Pt(bt)μ-(N^S)]2 complexes (bt-is the deprotonated form of 2-phenylbenzothiazole, (N^S)- = 2- mercaptopyridineate, 2-mercaptopyrimidineate, 2-mercaptobenzothiazoleate, 2-mercaptobenzoxazoleate ions) are characterized by the following methods: X-ray crystallography, 1H and 195Pt NMR spectroscopy, electronic absorption and emission spectroscopy, cyclic voltammetry. The occurrence of the Pt-Pt chemical bond and complexes in both crystalline state and solution in the form of cis-N(bt),S-binding isomers with the asymmetrical arrangement of two cyclometalated and two bridging ligands is shown. Long-wave absorption bands and luminescence of the complexes in the red spectral range are due to spin-allowed and spin-forbidden optical charge transfer transitions from the metal-metal bond to the metalated ligand. In cyclic voltammetry, two-electron redox waves of the complexes are attributed to metal- and ligand-centered processes involving σ∗HOMO and π∗(bt) LUMO of the complexes.
