Co3H2(C7O9)2(CH)6(C2O)2 is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of twelve 02329_fluka molecules, four dimethyl ether molecules, and two Co3H2(C7O9)2 clusters. In each Co3H2(C7O9)2 cluster, there are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(1), one O(4), one O(5), one O(6), and one O(7) atom to form distorted corner-sharing CoO5 square pyramids.

In the second Co site, Co(2) is bonded to two equivalent O(10), two equivalent O(5), and two equivalent O(9) atoms to form corner-sharing CoO6 octahedra. Both Co(2)-O(10) bond lengths are 2.04 Å. Both Co(2)-O(5) bond lengths are 2.14 Å. Both Co(2)-O(9) bond lengths are 2.13 Å. There are seven inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.27 Å. The C(1)-O(2) bond length is 1.26 Å.

In the fourth C site, C(5) is bonded in a distorted single-bond geometry to one C(12), one C(4), and one O(3) atom. The C(5)-C(12) bond length is 1.48 Å. The C(5)-O(3) bond length is 1.38 Å. In the fifth C site, C(6) is bonded in a distorted bent 120 degrees geometry to one O(4) and one O(5) atom. The C(6)-O(4) bond length is 1.25 Å. The C(6)-O(5) bond length is 1.28 Å. In the sixth C site, C(11) is bonded in a distorted bent 120 degrees geometry to one O(10) and one O(7) atom. The C(11)-O(10) bond length is 1.25 Å. The C(11)-O(7) bond length is 1.26 Å. In the seventh C site, C(12) is bonded in a distorted bent 120 degrees geometry to one C(5), one O(6), and one O(9) atom. The C(12)-O(6) bond length is 1.28 Å. The C(12)-O(9) bond length is 1.25 Å. H(2) is bonded in a single-bond geometry to one C(4) atom. There are nine 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 single-bond geometry to one C(1) atom. In the third O site, O(3) is bonded in a water-like geometry to one C(2) and one C(5) atom. In the fourth O site, O(4) is bonded in a distorted L-shaped geometry to one Co(1) and one C(6) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Co(1), one Co(2), and one C(6) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Co(1) and one C(12) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one Co(1) and one C(11) atom.
