CdH8(C3N)4(CH)6 crystallizes in the tetragonal I-42d space group. The structure consists of twenty-four 02329_fluka molecules inside a CdH8(C3N)4 framework. In the CdH8(C3N)4 framework, Cd(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. All Cd(1)-N(1) bond lengths are 2.21 Å. There are four inequivalent C sites. In the first C site, C(3) is bonded in a distorted single-bond geometry to one C(4) and one H(3) atom. The C(3)-C(4) bond length is 1.41 Å. The C(3)-H(3) bond length is 1.09 Å. In the second C site, C(4) is bonded in a trigonal planar geometry to one C(5) and two equivalent C(3) atoms. The C(4)-C(5) bond length is 1.47 Å. In the third C site, C(5) is bonded in a distorted trigonal planar geometry to one C(4) and two equivalent N(1) atoms. Both C(5)-N(1) bond lengths are 1.35 Å. In the fourth C site, C(6) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(4) atom. The C(6)-N(1) bond length is 1.38 Å. The C(6)-H(4) bond length is 1.08 Å. N(1) is bonded in a trigonal planar geometry to one Cd(1), one C(5), and one C(6) atom. There are two inequivalent H sites. In the first H site, H(3) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(4) is bonded in a single-bond geometry to one C(6) atom. Linkers: 4 [CH]1C=NC(c2ccccc2)=N1.
