On the synthesis and structural analysis of some coordination polymers derived from Hg(TeAr)2 involving dithio ligands

Hg(TePh)2 (Ph = phenyl) reacts with Hg(dedtc)2 (dedtc = diethyldithiocarbamate), as well as with Hg(dedtp)2 (dedtp = diethyldithiophosphate) and sodium pyrrolidine dithiocarbamate to give the coordination polymers [Hg(TePh)(S2CNEt2)]n (1), [Hg(TePh){S2P(OEt)2}]n (2), and [Hg(TePh)(S2CNC4H8)]n (3); Hg{Te(dmb)}2 (dmb = 2,6-dimethoxybenzene) and Hg{Te(mes)}2 (mes = 2,4,6-trimethylbenzene) react with NaS2CNC4H8 to yield the polymers [Hg{Te(dmb)(S2CNC4H8)}]n (4) and [Hg{Te(mes)(S2CNC4H8)}]n (5), as well as the mononuclear complexes [Hg(dmb)(S2CNC4H8)] (6) and [Hg(mes)(S2CNC4H8)] (7). The compounds 1, 2 and 3 present a helical structure along the Hg–Te bonds, while 4 and 5 show a zigzag arrangement. In 3, 4 and 5 each Hg atom is linked to two sulfur atoms of one dithio ligand. Compounds 6 and 7 are mononuclear, and probably also decomposition products of 4 and 5, respectively.
