HgC4H4(NCl)2(C9H6N)2(C2NH2)2 is Indium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight n-methyl methanimine molecules, eight schembl1705614 molecules, and four HgC4H4(NCl)2 clusters. In each HgC4H4(NCl)2 cluster, Hg(1) is bonded in a distorted trigonal pyramidal geometry to two equivalent N(1) and two equivalent Cl(1) atoms. Both Hg(1)-N(1) bond lengths are 2.47 Å. Both Hg(1)-Cl(1) bond lengths are 2.40 Å. There are two inequivalent C sites. In the first C site, C(4) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(2,4) atom. The C(4)-N(1) bond length is 1.35 Å. The C(4)-H(2,4) bond length is 1.09 Å. In the second C site, C(7) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(2,4) atom. The C(7)-N(1) bond length is 1.35 Å. The C(7)-H(2,4) bond length is 1.09 Å. N(1) is bonded in a distorted trigonal planar geometry to one Hg(1), one C(4), and one C(7) atom. H(2,4) is bonded in a single-bond geometry to one C(4) atom. Cl(1) is bonded in a single-bond geometry to one Hg(1) atom.
