VOAsO4 crystallizes in the orthorhombic Pnma space group. V(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms. As(1) is bonded in a tetrahedral geometry to one O(1), one O(4), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one V(1) and one As(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent V(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one As(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one V(1) and one As(1) atom.
