The compound described by Sr3Zn3Te(PO7)2 is Esseneite-derived structured and crystallizes in the trigonal P321 space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. Zn(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form ZnO4 tetrahedra that share corners with two equivalent Te(1)O6 octahedra and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 63°. P(1) is bonded to one O(2) and three equivalent O(3) atoms to form PO4 tetrahedra that share corners with three equivalent Zn(1)O4 tetrahedra. Te(1) is bonded to six equivalent O(1) atoms to form TeO6 octahedra that share corners with six equivalent Zn(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Sr(1), one Zn(1), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Sr(1) and one P(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one Zn(1), and one P(1) atom. is represented by the CIF card [CIF]
