Crystal and molecular structure of the 1 : 2 addition complex of bis(phenyldithioacetato)nickel(II) with pyridine

Abstract

Crystals of the title compound [Ni(PhCH₂·CHS₂)₂(py)₂] are monoclinic, space group C2/c, unit-cell dimensions a= 16.733(10), b= 10.853(5), c= 17.222(10)Å, β= 124.0(1)°, Z= 4. The crystal and molecular structure was determined from photographic X-ray data by the heavy atom method and refined by least squares to R 0.054. The monomeric unit consists of a distorted octahedron about the Ni atom which is situated on a two-fold axis. The pyridine molecules are cis-co-ordinated. l.r. and visible spectra are reported.
