The material described by AlBi(WO4)2 crystallizes in the monoclinic P2/c space group. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form WO6 octahedra that share corners with four equivalent Bi(1)O6 octahedra, corners with three equivalent Al(1)O4 tetrahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-64°. Al(1) is bonded to two equivalent O(3) and two equivalent O(4) atoms to form distorted AlO4 tetrahedra that share corners with two equivalent Bi(1)O6 octahedra and corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-60°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and corners with two equivalent Al(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 50-64°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one W(1) and one Bi(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent W(1) and one Bi(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one W(1), one Al(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Al(1) atom. is represented by the CIF file [CIF]
