The compound described by VMnO4 crystallizes in the orthorhombic Cmcm space group. V(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form VO4 tetrahedra that share corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-54°. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra and edges with two equivalent Mn(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one V(1) and one Mn(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one V(1) and two equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
