The material structure described by Pm2(WO4)3 crystallizes in the monoclinic C2/c space group. Pm(1) is bonded in a 8-coordinate geometry to one O(2), one O(4), one O(5), one O(6), two equivalent O(1), and two equivalent O(3) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 5-coordinate geometry to one O(3), one O(5), one O(6), and two equivalent O(4) atoms. In the second W site, W(2) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are six inequivalent O sites. In the first O site, O(4) is bonded in a trigonal non-coplanar geometry to one Pm(1) and two equivalent W(1) atoms. In the second O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Pm(1) and one W(1) atom. In the third O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Pm(1) and one W(1) atom. In the fourth O site, O(1) is bonded in a trigonal planar geometry to two equivalent Pm(1) and one W(2) atom. In the fifth O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Pm(1) and one W(2) atom. In the sixth O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Pm(1) and one W(1) atom. is represented by the CIF file [CIF]
