The structure described by NaGeSbO5 crystallizes in the monoclinic C2/c space group. Na(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(3), and four equivalent O(2) atoms. Ge(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form GeO4 tetrahedra that share corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-55°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra and corners with four equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Na(1) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Ge(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Na(1), one Ge(1), and one Sb(1) atom. is represented by the CIF file [CIF]
