Co(CO2)4(C5N2H7)2 is Indium-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four 1,3-dimethyl-2h-imidazole molecules and two Co(CO2)4 clusters. In each Co(CO2)4 cluster, Co(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(5), and one O(6) atom. The Co(1)-O(1) bond length is 1.95 Å. The Co(1)-O(2) bond length is 1.95 Å. The Co(1)-O(5) bond length is 1.95 Å. The Co(1)-O(6) bond length is 1.95 Å. There are four inequivalent C sites. In the first C site, C(5) is bonded in a distorted bent 120 degrees geometry to one O(5) and one O(7) atom. The C(5)-O(5) bond length is 1.30 Å. The C(5)-O(7) bond length is 1.24 Å. In the second C site, C(6) is bonded in a distorted bent 120 degrees geometry to one O(6) and one O(8) atom. The C(6)-O(6) bond length is 1.30 Å. The C(6)-O(8) bond length is 1.24 Å. In the third C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(3) atom. The C(1)-O(1) bond length is 1.29 Å. The C(1)-O(3) bond length is 1.24 Å. In the fourth C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(4) atom. The C(2)-O(2) bond length is 1.29 Å. The C(2)-O(4) bond length is 1.24 Å. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Co(1) and one C(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Co(1) and one C(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one C(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one C(2) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Co(1) and one C(5) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Co(1) and one C(6) atom. In the seventh O site, O(7) is bonded in a single-bond geometry to one C(5) atom. In the eighth O site, O(8) is bonded in a single-bond geometry to one C(6) atom. Linkers: 4 [O]C(=O)CN1[CH]N(CC([O])=O)C=C1. Metal clusters: 2 O=[C]O[Co](O[C]=O)(O[C]=O)O[C]=O. RCSR code: sql.
