The synthesis and characterisation of a variety of SbX3L1.5 (X = Cl or Br), BiCl3L2, SnX4L (X = Cl or Br), and TiCl4L complexes i, Bun, cyclo-C6H11, or CH2Ph> is described.In all cases metal-sulphur bonds are formed following SS'-bidentate ligand attachment.The potential N-donor sites are not involved in co-ordination.The structural characterisation of the uncomplexed ligand PriNHC(S)C(S)NHPri (L3) and the antimony(III) complex SbCl3(L3)1.5 (1) are reported.Crystals of (1) are rhombohedral, space group with a = 11.80(1) Angstroem, α = 60.1(1) deg, and Z = 2. 1089 Unique data above background were collected and the structure refinded to R 0.068.Crystals of L3 are monoclinic, space group P21/c with a = 6.226(7), b = 8.067(11), c = 11.187(12) Angstroem, β = 91.0(1) deg, and Z = 2. 635 Data above background were measured and the structure refinded to R 0.077.The structure of (1) is a three-dimensional polymer.The octahedrally co-ordinated Sb atom lies on a three-fold axis and is strongly bound to three chlorine atoms and also weakly bound to three sulphur atoms from different ligands, which approach their positions trans to chlorine thus giving rise to an octahedral environment.There is no evidence for a stereochemically active lone pair associated with SbIII.In the structure of L3 the sulphur atoms are mutually trans and this orientation is retained on complexation.
