The crystal structure described by WZnP2O7 crystallizes in the triclinic P-1 space group. W(1) is bonded to one O(2), one O(3), one O(4), one O(7), and two equivalent O(6) atoms to form WO6 octahedra that share corners with three equivalent P(1)O4 tetrahedra, corners with three equivalent P(2)O4 tetrahedra, and  an edgeedge with one W(1)O6 octahedra. Zn(1) is bonded in a distorted L-shaped geometry to two equivalent O(5) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(5), and one O(6) atom to form PO4 tetrahedra that share corners with three equivalent W(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 43-55°. In the second P site, P(2) is bonded to one O(1), one O(3), one O(4), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent W(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 34-47°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one W(1) and one P(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one W(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one W(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Zn(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one P(1) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one W(1) and one P(2) atom. is represented by the CIF file [CIF]
