The crystal structure described by Pr5Ge3O13 crystallizes in the hexagonal P6_3/m space group. There are two inequivalent Pr sites. In the first Pr site, Pr(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 Pr site, Pr(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 Pr(2) atoms. In the second O site, O(4) is bonded in a 4-coordinate geometry to one Pr(2), two equivalent Pr(1), and one Ge(1) atom. In the third O site, O(1) is bonded in a 4-coordinate geometry to one Pr(2), two equivalent Pr(1), and one Ge(1) atom. In the fourth O site, O(2) is bonded in a 4-coordinate geometry to one Pr(1), two equivalent Pr(2), and one Ge(1) atom. is represented by the CIF card [CIF]
