(HgCl2)3(C3S2H4)2 is Indium-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one 1,3-dithiolane, 2-(1,3-dithiolan-2-ylidene)- molecule and one HgCl2 cluster. In the HgCl2 cluster, there are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted square co-planar geometry to two equivalent Cl(1) and two equivalent Cl(3) atoms. Both Hg(1)-Cl(1) bond lengths are 2.37 Å. Both Hg(1)-Cl(3) bond lengths are 2.98 Å. In the second Hg site, Hg(2) is bonded in a linear geometry to one Cl(2) and one Cl(3) atom. The Hg(2)-Cl(2) bond length is 2.37 Å. The Hg(2)-Cl(3) bond length is 2.39 Å. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Hg(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Hg(2) atom. In the third Cl site, Cl(3) is bonded in a distorted water-like geometry to one Hg(1) and one Hg(2) atom. Linkers: 2 [CH]1CSC(=C2SCCS2)S1 ,1 C1CSC(=C2SCCS2)S1. Metal clusters: 3 [Hg]. The MOF has largest included sphere 1.80 A, density 3.65 g/cm3, surface area 2242.82 m2/g, accessible volume 0.04 cm3/g
