The material described by W3Zn3As4O16 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(4), one O(5), one O(7), and one O(8) atom to form WO6 octahedra that share  a cornercorner with one Zn(1)O4 tetrahedra,  an edgeedge with one Zn(2)O6 octahedra, and  an edgeedge with one Zn(1)O4 tetrahedra. In the second W site, W(2) is bonded in a square co-planar geometry to two equivalent O(5) and two equivalent O(7) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form distorted ZnO4 tetrahedra that share  a cornercorner with one W(1)O6 octahedra and  an edgeedge with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 53°. In the second Zn site, Zn(2) is bonded to two equivalent O(2), two equivalent O(6), and two equivalent O(8) atoms to form ZnO6 octahedra that share edges with two equivalent W(1)O6 octahedra. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 3-coordinate geometry to one O(1), one O(4), and one O(6) atom. In the second As site, As(2) is bonded in a water-like geometry to one O(2) and one O(3) atom. There are eight inequivalent O sites. In the first O site, O(7) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. In the second O site, O(8) is bonded in a distorted water-like geometry to one W(1) and one Zn(2) atom. In the third O site, O(1) is bonded in a trigonal planar geometry to one W(1), one Zn(1), and one As(1) atom. In the fourth O site, O(2) is bonded in a distorted trigonal planar geometry to one W(1), one Zn(2), and one As(2) atom. In the fifth O site, O(3) is bonded in a bent 120 degrees geometry to one Zn(1) and one As(2) atom. In the sixth O site, O(4) is bonded in a trigonal planar geometry to one W(1), one Zn(1), and one As(1) atom. In the seventh O site, O(5) is bonded in a distorted trigonal planar geometry to one W(1), one W(2), and one Zn(1) atom. In the eighth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Zn(2) and one As(1) atom. is represented by the CIF card [CIF]
