The material structure described by Na2LuC2O6F crystallizes in the monoclinic C2/c space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(5), one O(6), and one F(1) atom. In the second Na site, Na(2) is bonded in a 5-coordinate geometry to one O(5), two equivalent O(4), and two equivalent O(6) atoms. Lu(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(4), one O(5), two equivalent O(3), and two equivalent F(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1), one Lu(1), and one C(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Na(1), one Lu(1), and one C(1) atom. In the third O site, O(6) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Na(2), and one C(2) atom. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Lu(1), and one C(1) atom. In the fifth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Na(2), one Lu(1), and one C(2) atom. In the sixth O site, O(5) is bonded in a distorted see-saw-like geometry to one Na(1), one Na(2), one Lu(1), and one C(2) atom. F(1) is bonded in a trigonal non-coplanar geometry to one Na(1) and two equivalent Lu(1) atoms. is represented by the CIF file [CIF]
