Abstract

The central antimony atom in Sb[S2CN(Me)CH2CH 2OH]3 • MeOH is asymmetrically chelated by three dithiocarbamate ligands leading to a six-coordinate geometry that defines a distorted octahedron; the lone-pair of electrons projects out through the triangular face defined by the three sulphur atoms forming the longer Sb-S bonds. Centrosymmetrically related molecules associate via weak Sb•••S interactions to form dimeric aggregates. The crystal packing is dominated by O-H•••O interactions involving both the ethanol residues and solvent methanol molecules via a 16-membered [O-H•••]8 ring. These extend in two dimensions to form a layer architecture. The compound crystallizes in the triclinic space group P-1 with a = 9.1917(10) Å, b = 9.5326(10) Å, c = 15.5448(17) Å, α = 69.038(14)°, β = 70.506(15)°, γ = 70.447(16)°, and Z = 2.
