NaGeSb5O crystallizes in the monoclinic C2/c space group. Na(1) is bonded in a distorted single-bond geometry to two equivalent Ge(1), one Sb(1), two equivalent Sb(2), and one O(1) atom. Ge(1) is bonded in a 8-coordinate geometry to two equivalent Na(1), two equivalent Sb(1), two equivalent Sb(2), and two equivalent Sb(3) atoms. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 5-coordinate geometry to one Na(1), two equivalent Ge(1), and two equivalent Sb(2) atoms. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to one Na(1), one Ge(1), one Sb(1), one Sb(2), and two equivalent Sb(3) atoms. In the third Sb site, Sb(3) is bonded in a distorted single-bond geometry to one Ge(1), two equivalent Sb(2), and one O(1) atom. O(1) is bonded in a distorted trigonal non-coplanar geometry to one Na(1) and two equivalent Sb(3) atoms.
