VC14H8O5 crystallizes in the orthorhombic Imma space group. V(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 48°. Both V(1)-O(2) bond lengths are 1.91 Å. All V(1)-O(1) bond lengths are 1.82 Å. There are five inequivalent C sites. In the first C site, C(2) is bonded in a distorted trigonal planar geometry to one C(1), one C(5), and one H(2) atom. The C(2)-C(1) bond length is 1.47 Å. The C(2)-C(5) bond length is 1.46 Å. The C(2)-H(2) bond length is 1.14 Å. In the second C site, C(1) is bonded in a distorted single-bond geometry to one C(2), one C(4), and one H(1) atom. The C(1)-C(4) bond length is 1.46 Å. The C(1)-H(1) bond length is 1.14 Å. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one C(4) and two equivalent O(1) atoms. The C(3)-C(4) bond length is 1.53 Å. Both C(3)-O(1) bond lengths are 1.35 Å. In the fourth C site, C(4) is bonded in a trigonal planar geometry to one C(3) and two equivalent C(1) atoms. In the fifth C site, C(5) is bonded in a trigonal planar geometry to one C(5) and two equivalent C(2) atoms. The C(5)-C(5) bond length is 1.49 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent V(1) atoms. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one V(1) and one C(3) atom.
