@article {15334, title = {A crystallographic and spectroscopic study of mercury(II) dithiocarbamate}, journal = {Canadian Journal of Chemistry}, volume = {59}, year = {1981}, pages = {2746-2749}, abstract = {Ammonium dithiocarbamate, H2NCS2NH4, decomposes easily but the anion forms a stable mercury(II) complex, the crystals of which are orthorhombic with\ a = 7.851(3),\ b = 17.565(7),\ c = 12.051(3) {\r A}, and space group\ Pbca. The structure was solved by the Patterson method and refined by the full-matrix least-squares method to an\ R\ of 0.038 for 781 reflections. The structure consists of layers of two-dimensional polymeric networks. The dimeric subunits in the layer containing two each of mutually connected Hg atoms and dithiocarbamates are further linked by other bridging dithiocarbamates forming a sheet-like structure. Each Hg atom bonds to four S atoms from four separate dithiocarbamates with Hg{\textemdash}S distances of 2.499(4), 2.508(4), 2.533(4), and 2.629(4) {\r A}. The ir bands observed were: ν(NH2), 3320, 3220, 3125; δ(NH2), 1600; ν(C{\textemdash}N), 1395; ρr(NH2), 1172; and v(C{\textemdash}S), 840 cm-1. The mass spectrum of this polymeric compound gave peaks corresponding to Hg, S2, CNH2, HNCS, S, CS2, S5, S4, S3, and S8\ in the order of their intensities.}, url = {https://doi.org/10.1139/v81-396}, author = {Chung Chieh and Sing Kwen Cheung} }
