The material described by Na2PrGeO5 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 5-coordinate geometry to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms. Pr(1) is bonded in a 8-coordinate geometry to one O(2), one O(4), two equivalent O(3), and four equivalent O(1) atoms. Ge(1) is bonded in a tetrahedral geometry to one O(2), one O(4), and two equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Pr(1), and one Ge(1) atom. In the second O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Na(1), two equivalent Pr(1), and one Ge(1) atom. In the third O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Na(1), one Pr(1), and one Ge(1) atom. In the fourth O site, O(3) is bonded in a see-saw-like geometry to two equivalent Na(1) and two equivalent Pr(1) atoms. is represented by the CIF card [CIF]
