	abstract = {Ammonium dithiocarbamate, H2NCS2NH4, decomposes easily but the anion forms a stable mercury(II) complex, the crystals of which are orthorhombic with\&nbsp;a = 7.851(3),\&nbsp;b = 17.565(7),\&nbsp;c = 12.051(3) {\r A}, and space group\&nbsp;Pbca. The structure was solved by the Patterson method and refined by the full-matrix least-squares method to an\&nbsp;R\&nbsp;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\&nbsp;in the order of their intensities.},
