The polymer complex [Hg(mu-mptrz)(2)] (n) and two binuclear complexes of {[H(2)en][Hg-2(mptrz)(4)(mu-Br)(2)]} and {[H(2)en][Hg-2(mptrz)(4)(mu-I)(2)]} were prepared from the reaction of 4-methyl-1,2,4-triazole-3-thiol (Hmptrz) and ethylene diamine (en) with HgCl2, HgBr2, and HgI2 in CH3OH, respectively. Complex [Hg(mu-mptrz)(2)] (n) was also prepared from the reaction of 4-methyl-1,2,4-triazole-3-thiol and ethylene diamine with Hg(OAc)(2) and Hg(SCN)(2) in CH3OH and Hg(NO3)(2)center dot H2O in a mixture of CH3OH/H2O. Analysis of these complexes was done by CHN elemental analysis, IR, UV-Vis, H-1 and C-13 NMR, and luminescence spectroscopy, as well as single-crystal X-ray diffraction. Thermal stabilities of these complexes were also studied by TGA/DTA analyses.
