Sr2UZnO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. U(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form UO6 octahedra that share corners with six equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-26°. Zn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form ZnO6 octahedra that share corners with six equivalent U(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-26°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one U(1), and one Zn(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one U(1), and one Zn(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one U(1), and one Zn(1) atom.
