The structure described by Ni2Sr(VO4)2 crystallizes in the tetragonal I4_1cd space group. Sr(1) is bonded in a 10-coordinate geometry to two equivalent O(2), two equivalent O(3), two equivalent O(4), and four equivalent O(1) atoms. V(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form VO4 tetrahedra that share corners with six equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-57°. Ni(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form NiO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra and edges with two equivalent Ni(1)O6 octahedra. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and one Ni(1) atom. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one V(1), and one Ni(1) atom. In the third O site, O(2) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and two equivalent Ni(1) atoms. In the fourth O site, O(3) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and two equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
