The crystal structure described by KV3O8 crystallizes in the monoclinic P2_1/m space group. K(1) is bonded in a 10-coordinate geometry to one O(2), one O(5), four equivalent O(3), and four equivalent O(4) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 5-coordinate geometry to one O(3), one O(4), one O(5), and two equivalent O(1) atoms. In the second V site, V(2) is bonded in a 6-coordinate geometry to one O(2), one O(5), two equivalent O(1), and two equivalent O(3) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(2) and two equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(1) and one V(2) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1), one V(1), and one V(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one V(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal pyramidal geometry to one K(1), one V(2), and two equivalent V(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
