The compound described by K3VO4 crystallizes in the tetragonal I-42m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to four equivalent O(1) atoms to form distorted KO4 trigonal pyramids that share corners with four equivalent V(1)O4 tetrahedra and corners with eight equivalent K(2)O4 tetrahedra. In the second K site, K(2) is bonded to four equivalent O(1) atoms to form KO4 tetrahedra that share corners with four equivalent K(2)O4 tetrahedra, corners with four equivalent V(1)O4 tetrahedra, and corners with four equivalent K(1)O4 trigonal pyramids. V(1) is bonded to four equivalent O(1) atoms to form VO4 tetrahedra that share corners with eight equivalent K(2)O4 tetrahedra and corners with four equivalent K(1)O4 trigonal pyramids. O(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one V(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
