The structure was solved by the Patterson method and refined by the full-matrix least-squares method to an&amp;nbsp;&lt;i&gt;R&lt;/i&gt;&amp;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—S distances of 2.499(4), 2.508(4), 2.533(4), and 2.629(4) Å. The ir bands observed were: ν(NH&lt;sub&gt;2&lt;/sub&gt;), 3320, 3220, 3125; δ(NH&lt;sub&gt;2&lt;/sub&gt;), 1600; ν(C—N), 1395; ρ&lt;sub&gt;r&lt;/sub&gt;(NH&lt;sub&gt;2&lt;/sub&gt;), 1172; and v(C—S), 840 cm&lt;sup&gt;−1&lt;/sup&gt;. The mass spectrum of this polymeric compound gave peaks corresponding to Hg, S&lt;sub&gt;2&lt;/sub&gt;, CNH&lt;sub&gt;2&lt;/sub&gt;, HNCS, S, CS&lt;sub&gt;2&lt;/sub&gt;, S&lt;sub&gt;5&lt;/sub&gt;, S&lt;sub&gt;4&lt;/sub&gt;, S&lt;sub&gt;3&lt;/sub&gt;, and S&lt;sub&gt;8&lt;/sub&gt;&amp;nbsp;in the order of their intensities.</style></abstract><issue><style face="normal" font="default" size="100%">18</style></issue></record></records></xml>
