HgC5H4(NCl)2(CH)2(CH2)2 is Indium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of sixteen 02329_fluka molecules, sixteen 02329_fluka molecules, and four HgC5H4(NCl)2 clusters. In each HgC5H4(NCl)2 cluster, Hg(1) is bonded to one N(1), one N(2), one Cl(1), and two equivalent Cl(2) atoms to form distorted edge-sharing HgN2Cl3 square pyramids. The Hg(1)-N(1) bond length is 2.33 Å. The Hg(1)-N(2) bond length is 2.50 Å. The Hg(1)-Cl(1) bond length is 2.43 Å. There is one shorter (2.65 Å) and one longer (2.90 Å) Hg(1)-Cl(2) bond length. There are five inequivalent C sites. In the first C site, C(4) is bonded in a distorted single-bond geometry to one C(5) and one H(4) atom. The C(4)-C(5) bond length is 1.40 Å. The C(4)-H(4) bond length is 1.09 Å. In the second C site, C(5) is bonded in a distorted trigonal planar geometry to one C(4), one C(6), and one N(1) atom. The C(5)-C(6) bond length is 1.47 Å. The C(5)-N(1) bond length is 1.35 Å. In the third C site, C(6) is bonded in a distorted bent 120 degrees geometry to one C(5), one N(2), and one H(5) atom. The C(6)-N(2) bond length is 1.28 Å. The C(6)-H(5) bond length is 1.10 Å. In the fourth C site, C(7) is bonded in a distorted water-like geometry to one N(2) and one H(6) atom. The C(7)-N(2) bond length is 1.46 Å. The C(7)-H(6) bond length is 1.11 Å. In the fifth C site, C(1) is bonded in a distorted trigonal planar geometry to one N(1) and one H(1) atom. The C(1)-N(1) bond length is 1.34 Å. The C(1)-H(1) bond length is 1.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Hg(1), one C(1), and one C(5) atom. In the second N site, N(2) is bonded in a distorted bent 120 degrees geometry to one Hg(1), one C(6), and one C(7) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(4) is bonded in a single-bond geometry to one C(4) atom. In the third H site, H(5) is bonded in a single-bond geometry to one C(6) atom. In the fourth H site, H(6) is bonded in a single-bond geometry to one C(7) atom. There are two 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 an L-shaped geometry to two equivalent Hg(1) atoms.
