The structure described by Lu3O2F5 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 7-coordinate geometry to two equivalent O(1), two equivalent F(2), and three equivalent F(1) atoms. In the second Lu site, Lu(2) is bonded in a 8-coordinate geometry to four equivalent O(1), two equivalent F(2), and two equivalent F(3) atoms. O(1) is bonded to two equivalent Lu(1) and two equivalent Lu(2) atoms to form a mixture of edge and corner-sharing OLu4 tetrahedra. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Lu(1) atoms. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Lu(2) and two equivalent Lu(1) atoms. In the third F site, F(3) is bonded in a 2-coordinate geometry to two equivalent Lu(2) atoms. is represented by the CIF file [CIF]
