The crystal is monoclinic:&amp;nbsp;&lt;i&gt;a&lt;/i&gt; = 8.966(11),&amp;nbsp;&lt;i&gt;b&lt;/i&gt; = 6.817(9),&amp;nbsp;&lt;i&gt;c&lt;/i&gt; = 12.092(14) Å, β = 100.3(1)°, and space group&amp;nbsp;&lt;i&gt;P&lt;/i&gt;2&lt;sub&gt;1&lt;/sub&gt;/&lt;i&gt;c&lt;/i&gt;&amp;nbsp;with four molecules per unit cell. The tsc is a bidentate ligand in this complex with Hg—S = 2.417(6) Å, Hg—N = 2.51(2) Å. The mercury atom is trigonal pyramidally four-coordinated, with two Hg—Cl distances of 2.366(6) and 2.770(5) Å. When the tsc is coordinated to the mercury(II) ions, the chemical shift of the&amp;nbsp;&lt;sup&gt;1&lt;/sup&gt;H atoms on the NH&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;and NH groups shift to a lower field.</style></abstract><issue><style face="normal" font="default" size="100%">22</style></issue></record></records></xml>
