CoH12(C4N)4(CH)4 crystallizes in the tetragonal I4_1/acd space group. The structure consists of thirty-two 02329_fluka molecules inside a CoH12(C4N)4 framework. In each CoH12(C4N)4 framework, Co(1) is bonded in a square co-planar geometry to four equivalent N(1) atoms. All Co(1)-N(1) bond lengths are 2.18 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1) atom. The C(1)-N(1) bond length is 1.35 Å. The C(1)-H(1) bond length is 0.93 Å. In the second 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 1.39 Å. The C(3)-H(3) bond length is 0.93 Å. In the third C site, C(4) is bonded in a trigonal planar geometry to one C(3), one C(4), and one C(5) atom. The C(4)-C(4) bond length is 1.49 Å. The C(4)-C(5) bond length is 1.39 Å. In the fourth C site, C(5) is bonded in a distorted bent 120 degrees geometry to one C(4), one N(1), and one H(4) atom. The C(5)-N(1) bond length is 1.34 Å. The C(5)-H(4) bond length is 0.93 Å. N(1) is bonded in a trigonal planar geometry to one Co(1), one C(1), and one C(5) atom. There are three 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(3) 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. Linkers: 17 c1cncc(-c2cccnc2)c1. Metal clusters: 8 [Co].
