The material structure described by Er2WO6 crystallizes in the monoclinic P2/c space group. There are three inequivalent Er sites. In the first Er site, Er(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), one O(5), one O(6), and two equivalent O(2) atoms. In the second Er site, Er(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. In the third Er site, Er(3) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(6) atoms. W(1) is bonded in a distorted octahedral geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Er(1), one Er(3), and one W(1) atom. In the second O site, O(1) is bonded to one Er(1), one Er(2), one Er(3), and one W(1) atom to form a mixture of edge and corner-sharing OEr3W tetrahedra. In the third O site, O(2) is bonded to one Er(3), two equivalent Er(1), and one W(1) atom to form a mixture of edge and corner-sharing OEr3W tetrahedra. In the fourth O site, O(3) is bonded to one Er(1), one Er(2), one Er(3), and one W(1) atom to form a mixture of distorted edge and corner-sharing OEr3W tetrahedra. In the fifth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Er(1), one Er(2), and one W(1) atom. In the sixth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Er(1), one Er(2), and one W(1) atom. is represented by the CIF card [CIF]
