The compound described by K2Sr(VO3)4 crystallizes in the tetragonal P4/nbm space group. K(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form KO6 octahedra that share corners with eight equivalent V(1)O4 tetrahedra. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. V(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form VO4 tetrahedra that share corners with four equivalent K(1)O6 octahedra and corners with two equivalent V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 59-72°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one K(1), one Sr(1), and one V(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1) and two equivalent V(1) atoms. is represented by the CIF card [CIF]
