VC8H4O5 crystallizes in the orthorhombic Pnma space group. V(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 48°. Both V(1)-O(1) bond lengths are 1.98 Å. There is one shorter (1.65 Å) and one longer (2.10 Å) V(1)-O(2) bond length. Both V(1)-O(3) bond lengths are 1.98 Å. There are four inequivalent C sites. In the first C site, C(3) is bonded in a distorted trigonal planar geometry to one C(2), one C(4), and one H(1) atom. The C(3)-C(2) bond length is 1.40 Å. The C(3)-C(4) bond length is 1.39 Å. The C(3)-H(1) bond length is 1.09 Å. In the second C site, C(4) is bonded in a distorted trigonal planar geometry to one C(2), one C(3), and one H(2) atom. The C(4)-C(2) bond length is 1.41 Å. The C(4)-H(2) bond length is 1.09 Å. In the third C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one O(1), and one O(3) atom. The C(1)-C(2) bond length is 1.48 Å. The C(1)-O(1) bond length is 1.28 Å. The C(1)-O(3) bond length is 1.28 Å. In the fourth C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(3), and one C(4) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(4) atom. There are three inequivalent O sites. In the first O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent V(1) atoms. In the third O site, O(1) is bonded in a bent 120 degrees geometry to one V(1) and one C(1) atom. Linkers: 4 [O]C(=O)c1ccc(C([O])=O)cc1. Metal clusters: 4 [V]. RCSR code: lvt.
