The material described by K2Bi(PO4)(WO4) crystallizes in the orthorhombic Ibca space group. K(1) is bonded in a 8-coordinate geometry to one O(3), two equivalent O(1), two equivalent O(4), and three equivalent O(2) atoms. W(1) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form WO4 tetrahedra that share corners with two equivalent Bi(1)O8 hexagonal bipyramids. Bi(1) is bonded to two equivalent O(1), two equivalent O(4), and four equivalent O(3) atoms to form distorted BiO8 hexagonal bipyramids that share corners with two equivalent W(1)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, edges with two equivalent Bi(1)O8 hexagonal bipyramids, and edges with two equivalent P(1)O4 tetrahedra. P(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with two equivalent Bi(1)O8 hexagonal bipyramids and edges with two equivalent Bi(1)O8 hexagonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1), one Bi(1), and one P(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent K(1) and one W(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one K(1), two equivalent Bi(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent K(1), one W(1), and one Bi(1) atom. is represented by the CIF card [CIF]
