V(CO3)2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one V(CO3)2 cluster. V(1) is bonded in a 1-coordinate geometry to one C(1), one O(1), one O(3), and one O(4) atom. The V(1)-C(1) bond length is 1.18 Å. The V(1)-O(1) bond length is 1.58 Å. The V(1)-O(3) bond length is 2.45 Å. The V(1)-O(4) bond length is 1.61 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 2-coordinate geometry to one V(1), one O(1), one O(4), and one O(5) atom. The C(1)-O(1) bond length is 1.41 Å. The C(1)-O(4) bond length is 1.72 Å. The C(1)-O(5) bond length is 0.92 Å. In the second C site, C(2) is bonded in a 3-coordinate geometry to one O(2), one O(3), and one O(6) atom. The C(2)-O(2) bond length is 0.92 Å. The C(2)-O(3) bond length is 1.72 Å. The C(2)-O(6) bond length is 1.41 Å. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one V(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(2) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one V(1) and one C(2) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one V(1) and one C(1) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one C(1) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one C(2) atom.
