The material described by V2AsO6 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(3), one O(4), one O(6), and two equivalent O(5) atoms to form VO6 octahedra that share corners with two equivalent V(1)O6 octahedra, corners with two equivalent V(2)O6 octahedra, corners with three equivalent As(1)O4 tetrahedra, and edges with two equivalent V(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-51°. In the second V site, V(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form VO6 octahedra that share corners with two equivalent V(1)O6 octahedra, corners with four equivalent As(1)O4 tetrahedra, and edges with two equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-51°. As(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form AsO4 tetrahedra that share corners with three equivalent V(1)O6 octahedra and corners with four equivalent V(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-60°. There are six inequivalent O sites. In the first O site, O(6) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one V(2) and one As(1) atom. In the third O site, O(2) is bonded in a trigonal planar geometry to one V(1), one V(2), and one As(1) atom. In the fourth O site, O(3) is bonded in a trigonal planar geometry to one V(1), one V(2), and one As(1) atom. In the fifth O site, O(4) is bonded in a distorted trigonal planar geometry to one V(1), one V(2), and one As(1) atom. In the sixth O site, O(5) is bonded in a trigonal planar geometry to one V(2) and two equivalent V(1) atoms. is represented by the CIF file [CIF]
