Synthesis and crystal structure of bis(1-oxopyridine-2-thiolato)phenylbismuth

Abstract

The title compound, a principal product of the reaction of acetato(diphenyl)bismuth and sodium 1-oxopyridine-2-thiolate, has been synthesised and its structure determined by X-ray crystallography from diffractometer data. Crystals are monoclinic, a= 21·157, b= 8·813, c= 8·944 Å, all ±0·005 Å, β= 96·74 ± 0·05°, space-group P2₁/a, Z= 4. The structure was solved by Patterson and Fourier methods and refined by least-squares techniques to R 3·9% for 931 reflections. The co-ordination about the bismuth atom was found to be a distorted octahedron with a pair of electrons presumably occupying a co-ordination site. The sulphur and oxygen atoms are in a cis-configuration.
