Complexes of mercury. Part IV. Crystal and molecular structure of the adduct of mercury dimethoxide and phenyl isothiocyanate

Abstract

The adduct of mercury dimethoxide and phenyl isothiocyanate, [PhN:C(OMe)S]₂Hg, crystallises in the monoclinic system, space group P2₁/c, with four molecules in a cell of dimensions a= 14·12, b= 6·19, c= 21·10 Å, β= 106° 42′. The average Hg–S bond length is 2·33 Å, and the S–Hg–S angle is 175°. The oxygen atoms in the molecule are 2·86 and 2·97 Å from the mercury atom. The immediate environment of the mercury atom is completed by two benzene carbon atoms and a sulphur atom of an adjacent molecule, with Hg⋯C distances of 3·41 and 3·47 Å, and Hg⋯S = 3·54 Å.
