CdC4N5H5ClCH crystallizes in the monoclinic P2_1/c space group. The structure consists of four 02329_fluka molecules inside a CdC4N5H5Cl framework. In the CdC4N5H5Cl framework, Cd(1) is bonded to one N(1), one N(3), one N(4), one N(5), and two equivalent Cl(1) atoms to form edge-sharing CdN4Cl2 octahedra. The Cd(1)-N(1) bond length is 2.38 Å. The Cd(1)-N(3) bond length is 2.37 Å. The Cd(1)-N(4) bond length is 2.33 Å. The Cd(1)-N(5) bond length is 2.47 Å. There is one shorter (2.60 Å) and one longer (2.68 Å) Cd(1)-Cl(1) bond length. There are four inequivalent C sites. In the first C site, C(2) is bonded in a distorted trigonal planar geometry to one C(1), one C(3), and one N(5) atom. The C(2)-C(1) bond length is 1.40 Å. The C(2)-C(3) bond length is 1.40 Å. The C(2)-N(5) bond length is 1.40 Å. In the second C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one H(2) atom. The C(3)-H(2) bond length is 1.09 Å. In the third C site, C(5) is bonded in a distorted bent 120 degrees geometry to one N(4) and one H(4) atom. The C(5)-N(4) bond length is 1.34 Å. The C(5)-H(4) bond length is 1.09 Å. In the fourth C site, C(1) is bonded in a distorted trigonal planar geometry to one C(2), one N(4), and one H(1) atom. The C(1)-N(4) bond length is 1.34 Å. The C(1)-H(1) bond length is 1.09 Å. There are five inequivalent N sites. In the first N site, N(5) is bonded in a 3-coordinate geometry to one Cd(1), one C(2), one H(5), and one H(6) atom. The N(5)-H(5) bond length is 1.03 Å. The N(5)-H(6) bond length is 1.03 Å. In the second N site, N(4) is bonded in a trigonal planar geometry to one Cd(1), one C(1), and one C(5) atom. In the third N site, N(1) is bonded in a linear geometry to one Cd(1) and one N(2) atom. The N(1)-N(2) bond length is 1.17 Å. In the fourth N site, N(2) is bonded in a linear geometry to one N(1) and one N(3) atom. The N(2)-N(3) bond length is 1.19 Å. In the fifth N site, N(3) is bonded in a bent 120 degrees geometry to one Cd(1) and one N(2) atom. There are five 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(3) atom. In the third H site, H(4) is bonded in a single-bond geometry to one C(5) atom. In the fourth H site, H(5) is bonded in a single-bond geometry to one N(5) atom. In the fifth H site, H(6) is bonded in a single-bond geometry to one N(5) atom. Cl(1) is bonded in an L-shaped geometry to two equivalent Cd(1) atoms. Linkers: 4 Nc1cccnc1 ,4 [N][N][N].
