N2 - The crystal structures of diaquabis[(benzylthio)acetato]zinc(II), [Zn(BTA)2 (H2O)2] (1), catena-[diaqua-tetra[(benzylthio)acetato)]-bis[cadmium(II)], [Cd2(BTA)4 H2O)2]n (2), catena-{tetra-μ-[2-methyl-3-(phenylthio)propionato-O,O′]-bis[copper (II)]}, [Cu2(MPTP)4]n (3) and tetra-μ-[2-methyl-2-(phenylthio)propionato-O,O′]- bis[ethanol copper(II)], [Cu2(PTIBA)4(EtOH)2] (4) have been determined using X-ray diffraction techniques. Complex (1) is monomeric with distorted octahedral stereochemistry and lies on a two-fold rotational axis. The MO6 coordination involves four oxygens from two slightly asymmetric bidentate BTA carboxyl groups [ZnO, 2.138(3), 2.28(3) Å] and two cis-related waters [ZnOw, 1.996(3) Å]. The cadmium complex (2) is best described in terms of a polymer with the repeating unit consisting of two different centres, one seven, the other six-coordinate. With the first, the distorted MO6S coordination sphere has four oxygens from two asymmetric bidentate carboxylate groups (ligands B and C) [CdO, 2.36, 2.56(1) Å; 2.26, 2.67(1) Å], an oxygen and a sulphur from a bidentate chelate ligand (A) [CdO, 2.36(1) Å; CdS, 2.773(4) Å] and an oxygen from a bridging carboxyl group (ligand D) [CdO, 2.28(1) Å]. Ligands C and D also bridge two Cd centres through sulphurs [CdS, 2.739, 2.723(4) Å]. The second carboxyl oxygen of ligand A also forms a bridge to the second Cd [(CdO, 2.30(1) Å], while the distorted octahedral MO4S2 stereochemistry is completed by two waters [CdO, 2.25(1), 2.49(1) Å] and a sulphur from ligand D [CdS, 2.723(4) Å] giving a polymer structure. Complexes (3) and (4) are centrosymmetric tetra-carboxylate bridged dimers [for (3) Cu ··· Cu, 2.586(3) Å; mean CuO(equatorial), 1.957(11) Å; for the two independent dimers in (4), Cu ··· Cu, 2.596(1), 2.616(1) Å; CuO (equatorial), 1.952(4), 1.968(4) Å mean]. The axial positions of the dimer in (3) are occupied by carboxyl oxygens of adjacent dimers [CuO, 2.280(9) Å] forming a polymer structure. In contrast, these positions in (4) are occupied by ethanol molecules with CuO, 2.222(3) and 2.177(4) Å respectively for the two independent dimers.
