The compound described by Na3GeCPO7 crystallizes in the monoclinic P2_1/m 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(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. Ge(1) is bonded in a 5-coordinate geometry to one O(2), one O(5), one O(6), and two equivalent O(4) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. P(1) is bonded in a tetrahedral geometry to one O(5), one O(6), and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Na(1), two equivalent Na(2), and one C(1) atom to form distorted ONa4C trigonal bipyramids that share corners with two equivalent O(1)Na4C trigonal bipyramids and  an edgeedge with one O(5)Na2GeP tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Na(2), one Ge(1), and one C(1) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to one Na(1), two equivalent Na(2), and one C(1) atom. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to one Na(1), one Na(2), one Ge(1), and one P(1) atom. In the fifth O site, O(5) is bonded to two equivalent Na(2), one Ge(1), and one P(1) atom to form distorted edge-sharing ONa2GeP tetrahedra. In the sixth O site, O(6) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(2), one Ge(1), and one P(1) atom. is represented by the CIF card [CIF]
