VMoO5 crystallizes in the monoclinic Cm space group. V(1) is bonded to one O(1), one O(3), one O(4), one O(5), and two equivalent O(2) atoms to form distorted corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 35°. Mo(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and two equivalent O(5) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one V(1) and one Mo(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent V(1) and one Mo(1) atom. In the third O site, O(3) is bonded in a linear geometry to one V(1) and one Mo(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to one V(1) and one Mo(1) atom. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one V(1) and two equivalent Mo(1) atoms.
