CoH8(C3O)4C8NH4 is Indium-derived structured and crystallizes in the orthorhombic Imma space group. The structure is zero-dimensional and consists of four n,n,n',n'-tetramethylbenzidine molecules and four CoH8(C3O)4 clusters. In each CoH8(C3O)4 cluster, Co(1) is bonded in a distorted square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Co(1)-O(1) bond lengths are 2.02 Å. Both Co(1)-O(2) bond lengths are 2.02 Å. There are six inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(4), one O(1), and one O(2) atom. The C(1)-C(4) bond length is 1.53 Å. The C(1)-O(1) bond length is 1.24 Å. The C(1)-O(2) bond length is 1.28 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(4), one C(5), and one H(1) atom. The C(2)-C(4) bond length is 1.39 Å. The C(2)-C(5) bond length is 1.39 Å. The C(2)-H(1) bond length is 0.93 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(6) and one H(2) atom. The C(3)-C(6) bond length is 1.37 Å. The C(3)-H(2) bond length is 0.93 Å. In the fourth C site, C(4) is bonded in a trigonal planar geometry to one C(1), one C(2), and one C(6) atom. The C(4)-C(6) bond length is 1.37 Å. In the fifth C site, C(5) is bonded in a distorted single-bond geometry to one C(2) and one H(3) atom. The C(5)-H(3) bond length is 0.93 Å. In the sixth C site, C(6) is bonded in a distorted trigonal planar geometry to one C(3), one C(4), and one H(4) atom. The C(6)-H(4) bond length is 0.93 Å. There are four inequivalent H sites. In the first H site, H(3) is bonded in a single-bond geometry to one C(5) atom. In the second H site, H(4) is bonded in a single-bond geometry to one C(6) atom. In the third H site, H(1) is bonded in a single-bond geometry to one C(2) atom. In the fourth H site, H(2) is bonded in a single-bond geometry to one C(3) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Co(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one C(1) atom.
