Treatment of the pentadentate macrocyclic ligand 4-(pyridin-2-ylmethyl)-1, 7-dithia-4,10-diazacyclododecane, L, and the hexadentate macrocyclic ligand 4,10-bis(pyridin-2-ylmethyl)-1,7-dithia-4,10-diazacyclododecane, L′, with one equivalent of a M2+ metal salt (M = Co, Ni, Cu) in methanol yielded six mononuclear complexes, [CoL(MeCN)](ClO4)2 (1), [NiL(H2O)]Cl2 (2), [CuL(MeCN)](ClO4) 2 (3) and [ML′](ClO4)2 (4-6). Their solid state crystal structures were determined using X-ray single crystal diffraction analysis. In complexes 1-3, the metal centres exhibit a slightly distorted octahedral geometry, resulting from the coordination of three nitrogen and two sulfur donating atoms in the ligand L and one solvent molecule (MeCN for complexes 1 and 3, water for complex 2) whereas in complexes 4-6, the coordination around the metal centres was satisfied by four nitrogen and two sulfur atoms from the ligand L′. The electronic spectra and electrochemistry of these complexes are reported
