(CH)2HgC10N4H8(OCl)2 is Indium-derived structured and crystallizes in the monoclinic P2/c space group. The structure is zero-dimensional and consists of four 02329_fluka molecules and two HgC10N4H8(OCl)2 clusters. In each HgC10N4H8(OCl)2 cluster, Hg(1) is bonded in a distorted see-saw-like geometry to two equivalent N(1) and two equivalent Cl(1) atoms. Both Hg(1)-N(1) bond lengths are 2.48 Å. Both Hg(1)-Cl(1) bond lengths are 2.39 Å. 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(5) atom. The C(4)-C(5) bond length is 1.40 Å. The C(4)-H(5) bond length is 1.09 Å. In the second C site, C(5) is bonded in a trigonal planar geometry to one C(1), one C(4), and one C(6) atom. The C(5)-C(1) bond length is 1.40 Å. The C(5)-C(6) bond length is 1.48 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 O(1) atom. The C(6)-N(2) bond length is 1.36 Å. The C(6)-O(1) bond length is 1.25 Å. In the fourth C site, C(1) is bonded in a distorted trigonal planar geometry to one C(5), one N(1), and one H(2) atom. The C(1)-N(1) bond length is 1.34 Å. The C(1)-H(2) bond length is 1.09 Å. In the fifth C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(3) atom. The C(2)-N(1) bond length is 1.34 Å. The C(2)-H(3) bond length is 1.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Hg(1), one C(1), and one C(2) atom. In the second N site, N(2) is bonded in a 2-coordinate geometry to one C(6) and one H(1) atom. The N(2)-H(1) bond length is 1.04 Å. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(2) atom. In the fourth H site, H(5) is bonded in a single-bond geometry to one C(4) atom. O(1) is bonded in a single-bond geometry to one C(6) atom. Cl(1) is bonded in a single-bond geometry to one Hg(1) atom. Linkers: 1 O=C(NNC(=O)c1cccnc1)c1cccnc1. Metal clusters: .
