Bi(WO4)2 crystallizes in the triclinic P-1 space group. W(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms. Bi(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one W(1) and one Bi(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one W(1) and one Bi(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to two equivalent W(1) and one Bi(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to two equivalent W(1) atoms.
