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