The crystal structure described by (KVO3)2O2 crystallizes in the orthorhombic Pnma space group. The structure consists of four water atoms inside a KVO3 framework. In the KVO3 framework, K(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. V(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), and three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and one V(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent K(1) and one V(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to three equivalent V(1) atoms. is represented by the CIF file [CIF]
