The compound described by K3V5O14 crystallizes in the trigonal P31m space group. K(1) is bonded in a 10-coordinate geometry to one O(3), two equivalent O(1), three equivalent O(2), and four equivalent O(4) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1) and three equivalent O(4) atoms to form corner-sharing VO4 tetrahedra. In the second V site, V(2) is bonded to one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent V(1)O4 tetrahedra and corners with two equivalent V(2)O5 trigonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one V(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent K(1) and one V(2) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one K(1) and two equivalent V(2) atoms. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to two equivalent K(1), one V(1), and one V(2) atom. is represented by the CIF card [CIF]
