VMnO4 crystallizes in the orthorhombic Imma 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 49-55°. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) 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 trigonal planar geometry to one V(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one V(1) and one Mn(1) atom.

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 49-55°. Both V(1)-O(1) bond lengths are 1.87 Å. Both V(1)-O(2) bond lengths are 1.67 Å. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra and edges with two equivalent Mn(1)O6 octahedra. Both Mn(1)-O(2) bond lengths are 2.24 Å. All Mn(1)-O(1) bond lengths are 1.98 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one V(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one V(1) and one Mn(1) atom.
