The structure described by Ge5O(PO4)6 crystallizes in the trigonal R-3 space group. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one O(3) and three equivalent O(2) atoms to form GeO4 tetrahedra that share  a cornercorner with one Ge(1)O4 tetrahedra and corners with three equivalent P(1)O4 tetrahedra. In the second Ge site, Ge(2) is bonded to three equivalent O(1) and three equivalent O(4) atoms to form GeO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. In the third Ge site, Ge(3) is bonded to six equivalent O(5) atoms to form GeO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form PO4 tetrahedra that share  a cornercorner with one Ge(3)O6 octahedra, corners with two equivalent Ge(2)O6 octahedra, and  a cornercorner with one Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 29-51°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ge(2) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Ge(1) and one P(1) atom. In the third O site, O(3) is bonded in a linear geometry to two equivalent Ge(1) atoms. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Ge(2) and one P(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Ge(3) and one P(1) atom. is represented by the CIF file [CIF]
