The formation and structural aspects of some metal complexes of thiosalicylic acid (TSA) were studied. The μ‐bridging tetra‐coordinated Ru complex, [Ru(C6H4(CO2)(μ‐S)(H2O)]2 (1) was formed by hydrothermal reaction of TSA with RuCl3. The complexes [M(dtdb)(phen)(H2O)]n (2–4) (M = ZnII, CoII, NiII, dtdb = 2,2′‐dithiodibenzoate anion, phen = 1,10‐phenanthroline) were obtained by the slow diffusion technique and the in situ S–S bond formation was confirmed by elemental, spectral and X‐ray analysis. Reaction of TSA with CuCl2 and 2,2′‐bipyridine (bipy) under the slow diffusion technique yielded the dimer [Cu(tdb)(bipy)] (5) (tdb = thiodibenzoic acid), where the in situ generation of 2,2′‐thiodibenzoic acid was observed.
Slow diffusion reaction of 2,2Ј-dithiodibenzoic acid (dtdb) with CuCl 2 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)(H 2 O)] 2 ·2H 2 O.2DMF] (1), [Cu(tdb)(py) 2 (H 2 O)] 2 (3), and [Cu(tdb)(bipy)(H 2 O)] 2 ·0.5H 2 O (4) (tdb = thiodibenzoic acid, phen = phenanthroline, py = pyridine, bipy = 2,2Ј-bipyridine) show * Dr. M.
