The structure described by CuZn(PO3)4 crystallizes in the monoclinic C2/c space group. Cu(1) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form CuO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra, and edges with two equivalent Zn(1)O6 octahedra. Zn(1) is bonded to two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms to form ZnO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with four equivalent P(2)O4 tetrahedra, and edges with two equivalent Cu(1)O6 octahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share  a cornercorner with one Zn(1)O6 octahedra, corners with two equivalent Cu(1)O6 octahedra, and corners with two equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 27-56°. In the second P site, P(2) is bonded to one O(1), one O(2), one O(5), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one Cu(1)O6 octahedra, corners with two equivalent Zn(1)O6 octahedra, and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 19-59°. There are six inequivalent O sites. In the first O site, O(3) is bonded in a bent 150 degrees geometry to one Cu(1) and one P(1) atom. In the second O site, O(4) is bonded in a distorted trigonal planar geometry to one Cu(1), one Zn(1), and one P(1) atom. In the third O site, O(5) is bonded in a distorted trigonal planar geometry to one Cu(1), one Zn(1), and one P(2) atom. In the fourth O site, O(6) is bonded in a bent 150 degrees geometry to one Zn(1) and one P(2) atom. In the fifth O site, O(1) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the sixth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one P(1) and one P(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
