Slow diffusion reaction of 2,2'-dithiodibenzoic acid (dtdb) with CuCl2 in the presence of N-donor ligands results in the formation of different coordination polymers where both S-S and C-S scission and oxidation of S is observed. X-ray diffraction analysis of [Cu(tdb)(phen)(H2O)](2)center dot 2H(2)O.2DMF] (1), [Cu(tdb)(Py)O-2(H2O)](2) (3), and [Cu(tdb)(bipy)(H2O)](2)-0.5H(2)O (4) (tdb = thiodibenzoic acid, phen = phenanthroline, py = pyridine, bipy = 2,2'-bipyridine) show that the metal ions are coordinated to the carboxylate oxygen atoms of the in situ generated tdb ligand in a monodenate fashion. In [Cu(pherI)(SO4)(2)(H2O)(2)], (2) and [Cu(birly)(SO4)(2)(H2O)]2], (5), the sulfur is oxidized to sulfate ions prior to coordination with the metal. Complex 1 has a dimeric structure with rc-tr interactions between the phon ligands, whereas 3 and 4 form ID polymeric chains.
