The material structure described by Nd5Ge3O13 crystallizes in the hexagonal P6_3/m space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(4) atoms. In the second Nd site, Nd(2) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), and four equivalent O(2) atoms. Ge(1) is bonded in a tetrahedral geometry to one O(1), one O(4), and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(3) is bonded in a trigonal planar geometry to three equivalent Nd(2) atoms. In the second O site, O(4) is bonded to one Nd(2), two equivalent Nd(1), and one Ge(1) atom to form distorted edge-sharing ONd3Ge tetrahedra. In the third O site, O(1) is bonded in a 4-coordinate geometry to one Nd(2), two equivalent Nd(1), and one Ge(1) atom. In the fourth O site, O(2) is bonded in a 4-coordinate geometry to one Nd(1), two equivalent Nd(2), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
