The crystal structure described by Cu3Ge(PO5)2 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a square co-planar geometry to two equivalent O(3) and two equivalent O(4) atoms. In the second Cu site, Cu(2) is bonded in a 6-coordinate geometry to one O(3), one O(4), one O(5), one O(6), and two equivalent O(7) atoms. Ge(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form GeO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra and  a cornercorner with one P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(2), one O(5), and two equivalent O(4) atoms to form PO4 tetrahedra that share  a cornercorner with one Ge(1)O4 tetrahedra. In the second P site, P(2) is bonded to one O(1), one O(6), and two equivalent O(7) atoms to form PO4 tetrahedra that share  a cornercorner with one Ge(1)O4 tetrahedra. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ge(1) and one P(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ge(1) and one P(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Cu(1), one Cu(2), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Cu(1), one Cu(2), and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent Cu(2) and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to two equivalent Cu(2) and one P(2) atom. In the seventh O site, O(7) is bonded in a 2-coordinate geometry to two equivalent Cu(2) and one P(2) atom. is represented by the CIF file [CIF]
