CdC6N6H8Cl crystallizes in the orthorhombic Imma space group. Cd(1) is bonded to four equivalent N(1) and two equivalent Cl(1) atoms to form corner-sharing CdN4Cl2 octahedra. The corner-sharing octahedral tilt angles are 86°. All Cd(1)-N(1) bond lengths are 2.34 Å. Both Cd(1)-Cl(1) bond lengths are 2.60 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(1) atom. The C(1)-N(1) bond length is 1.31 Å. The C(1)-N(2) bond length is 1.33 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(2) is bonded in a 4-coordinate geometry to one C(2), one N(2), and two equivalent H(2) atoms. The C(2)-C(2) bond length is 1.49 Å. The C(2)-N(2) bond length is 1.51 Å. Both C(2)-H(2) bond lengths are 0.97 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to one C(2) and two equivalent C(1) atoms. In the second N site, N(1) is bonded in a distorted trigonal planar geometry to one Cd(1), one C(1), and one N(1) atom. The N(1)-N(1) bond length is 1.38 Å. There are two 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(2) is bonded in a single-bond geometry to one C(2) atom. Cl(1) is bonded in an L-shaped geometry to two equivalent Cd(1) atoms. Linkers: 4 c1nncn1CCn1cnnc1. Metal clusters: 4 [Cd].
