@article {15335, title = {Synthesis and crystal structure of thiosemicarbazidedichloromercury(II)}, journal = {Canadian Journal of Chemistry}, volume = {55}, year = {1977}, pages = {3898-3900}, abstract = {Thiosemicarbazidedichloromercury(II) was synthesized in an ethanol{\textendash}water solution by keeping the molar ratio of HgCl2\ and thiosemicarbazide (tsc) at 1:1. The crystal is monoclinic:\ a = 8.966(11),\ b = 6.817(9),\ c = 12.092(14) {\r A}, β = 100.3(1){\textdegree}, and space group\ P21/c\ with four molecules per unit cell. The tsc is a bidentate ligand in this complex with Hg{\textemdash}S = 2.417(6) {\r A}, Hg{\textemdash}N = 2.51(2) {\r A}. The mercury atom is trigonal pyramidally four-coordinated, with two Hg{\textemdash}Cl distances of 2.366(6) and 2.770(5) {\r A}. When the tsc is coordinated to the mercury(II) ions, the chemical shift of the\ 1H atoms on the NH2\ and NH groups shift to a lower field.}, url = {https://doi.org/10.1139/v77-552}, author = {Chung Chieh and Dianna H.
