In the third C site, C(4) is bonded in a distorted single-bond geometry to one C(3) and one H(3) atom. The C(4)-H(3) bond length is 1.09 Å. In the fourth C site, C(6) is bonded in a distorted trigonal planar geometry to one C(3), one C(7), and one N(2) atom. The C(6)-C(7) bond length is 1.49 Å. The C(6)-N(2) bond length is 1.31 Å. In the fifth C site, C(7) is bonded in a trigonal non-coplanar geometry to one C(6), one H(5), one H(6), and one H(7) atom. The C(7)-H(5) bond length is 1.09 Å. The C(7)-H(6) bond length is 1.10 Å. The C(7)-H(7) bond length is 1.10 Å. N(2) is bonded in a distorted bent 120 degrees geometry to one C(6) and one N(2) atom. The N(2)-N(2) bond length is 1.37 Å. There are five inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(3) 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(7) atom. In the fourth H site, H(6) is bonded in a single-bond geometry to one C(7) atom. In the fifth H site, H(7) is bonded in a single-bond geometry to one C(7) atom. In each HgC6H4(N2S)2 cluster, Hg(1) is bonded in a distorted trigonal pyramidal geometry to two equivalent N(1) and two equivalent S(1) atoms. Both Hg(1)-N(1) bond lengths are 2.44 Å. Both Hg(1)-S(1) bond lengths are 2.48 Å. There are three inequivalent C sites. In the first C site, C(5) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1,4) atom. The C(5)-N(1) bond length is 1.34 Å. The C(5)-H(1,4) bond length is 1.09 Å. In the second C site, C(1) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1,4) atom. The C(1)-N(1) bond length is 1.35 Å. The C(1)-H(1,4) bond length is 1.09 Å. In the third C site, C(8) is bonded in a distorted single-bond geometry to one N(3) and one S(1) atom. The C(8)-N(3) bond length is 1.18 Å. The C(8)-S(1) bond length is 1.66 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(5) atom. In the second N site, N(3) is bonded in a single-bond geometry to one C(8) atom.
