The crystal structure described by Pb2Zn3Te2P2O14 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(1), one O(4), one O(6), and one O(7) atom to form ZnO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra. In the second Zn site, Zn(2) is bonded in a distorted square co-planar geometry to two equivalent O(3) and two equivalent O(5) atoms. Pb(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(5) atom. 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 corners with two equivalent Zn(1)O4 tetrahedra. Te(1) is bonded in a distorted rectangular see-saw-like geometry to one O(5), one O(7), and two equivalent O(6) atoms. There are seven inequivalent O sites. In the first O site, O(5) is bonded in a distorted trigonal planar geometry to one Zn(2), one Pb(1), and one Te(1) atom. In the second O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and two equivalent Te(1) atoms. In the third O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one Te(1) atom. In the fourth O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Zn(1), one Pb(1), and one P(1) atom. In the fifth O site, O(2) is bonded in a distorted single-bond geometry to one Pb(1) and one P(1) atom. In the sixth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Zn(2) and one P(1) atom. In the seventh O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
