The complexes Hg(SR)2 1 and a polymeric structure consisting of rather bent Hg(SR)2 units a very asymmetric bridge between two Hg atoms.Complex 2 contains Hg atoms in a distorted trigonal-planar co-ordination environment, the monomeric anions being well separated from each other.The distorsion is mostly in-plane, producing one angle considerably less than, and one considerably greater than, the ideal 120 deg; the largest angle lies opposite the longest Hg-S bond, and the smallest angle opposite the shortest Hg-S bond.Proton and 13C NMR, far-IR and Raman, and low-energy UV spectroscopic data are discussed.The UV data afford additional support for the proposal of a trigonal-planar A correlation of co-ordination geometry, Hg-S bond lengths, and Hg-S stretching frequencies is developed for these and other homoleptic thiolate complexes of mercury.
