The material described by VZnAs2O7 crystallizes in the monoclinic P2_1/c space group. V(1) is bonded to one O(1), one O(2), one O(5), one O(6), and one O(7) atom to form VO5 trigonal bipyramids that share corners with two equivalent As(1)O4 tetrahedra. Zn(1) is bonded in a 5-coordinate geometry to one O(1), one O(5), one O(7), and two equivalent O(3) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded to one O(2), one O(3), one O(4), and one O(6) atom to form AsO4 tetrahedra that share corners with two equivalent V(1)O5 trigonal bipyramids. In the second As site, As(2) is bonded in a 4-coordinate geometry to one O(4), one O(5), one O(6), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(5) is bonded in a distorted trigonal planar geometry to one V(1), one Zn(1), and one As(2) atom. In the second O site, O(6) is bonded in a 2-coordinate geometry to one V(1), one As(1), and one As(2) atom. In the third O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one V(1), one Zn(1), and one As(2) atom. In the fourth O site, O(1) is bonded in a bent 120 degrees geometry to one V(1) and one Zn(1) atom. In the fifth O site, O(2) is bonded in a linear geometry to one V(1) and one As(1) atom. In the sixth O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Zn(1) and one As(1) atom. In the seventh O site, O(4) is bonded in a bent 120 degrees geometry to one As(1) and one As(2) atom. is represented by the CIF file [CIF]
