The structure described by NaPr(CO3)2 crystallizes in the orthorhombic Pmc2_1 space group. Na(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(3), and four equivalent O(2) atoms. Pr(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(4), and four equivalent O(3) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one O(4) and two equivalent O(2) atoms. In the second C site, C(2) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Pr(1), and one C(2) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Pr(1), and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Pr(1), and one C(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Pr(1) and one C(1) atom. is represented by the CIF card [CIF]
