Abstract
The central antimony atom in Sb[S2CN(Me)CH2CH2OH]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.
