The structure described by KVPbO4 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), and four equivalent O(3) atoms. V(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. Pb(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(2) and two 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 one K(1) and one V(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1), one V(1), and two equivalent Pb(1) atoms. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1), one V(1), and one Pb(1) atom. is represented by the CIF file [CIF]
