New pyridine-based, tridentate, sulphur-containing ligands, 2,6-bis(ethylthiomethyl)pyridine, 2,6-bis(methoxycarbonylethylthiomethyl)pyridine, and 2,6- bis(benzylthiomethyl)pyridine, and their complexes with Zn, Cd, Cu, Co, and Ni are reported. The molecular structure of [2,6-bis(ethylthiomethyl)pyridine]dichlorocadmium(II) hydrate is also described. This compound is binuclear with bridging chlorine atoms, being triclinic, space group P1 with a = 8.267(2), b = 10.444(2), c = 11.825(3) Å, α = 64.98(2), β = 79.66(3), γ = 64.52(3)°, and Z = 1. For the complexes of Zn and Cu a mononuclear, five-co-ordinate structure is proposed, while for Cd, Co, and Ni binuclear structures with the metal ion in an octahedral arrangement and with bridging chlorine atoms are suggested.
