The material described by V3O7 is Potassium Silver Cyanide-derived structured and crystallizes in the tetragonal I4/mmm space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one O(1), two equivalent O(3), and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 0-28°. In the second V site, V(2) is bonded to two equivalent O(4) and four O(1,1) atoms to form corner-sharing VO6 octahedra. The corner-sharing octahedra are not tilted. In the third V site, V(3) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(5) atoms. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one V(1) and one V(2) atom. In the second O site, O(1) is bonded in a linear geometry to one V(1) and one V(2) atom. In the third O site, O(2) is bonded in a 3-coordinate geometry to three equivalent V(1) atoms. In the fourth O site, O(3) is bonded in a linear geometry to one V(1) and one V(3) atom. In the fifth O site, O(4) is bonded in a linear geometry to two equivalent V(2) atoms. In the sixth O site, O(5) is bonded to four equivalent V(3) atoms to form a mixture of distorted corner and edge-sharing OV4 tetrahedra. In the seventh O site, O(1) is bonded in a linear geometry to one V(1) and one V(2) atom. is represented by the CIF file [CIF]
