The material structure described by Na3Eu(CO3)3 crystallizes in the orthorhombic Ama2 space group. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to one O(4), one O(6), two equivalent O(1), and two equivalent O(2) atoms. In the second Na site, Na(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. In the third Na site, Na(3) is bonded in a 9-coordinate geometry to one O(4), one O(5), one O(6), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Eu(1) is bonded in a 9-coordinate geometry to one O(4), one O(5), one O(6), two equivalent O(1), two equivalent O(2), and two 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), one O(5), and one O(6) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are six inequivalent O sites. In the first O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Na(1), one Na(3), one Eu(1), and one C(1) atom. In the second O site, O(5) is bonded in a 5-coordinate geometry to one Na(3), two equivalent Na(2), one Eu(1), and one C(1) atom. In the third O site, O(6) is bonded in a distorted square co-planar geometry to one Na(1), one Na(3), one Eu(1), and one C(1) atom. In the fourth O site, O(1) is bonded to one Na(1), one Na(2), one Na(3), one Eu(1), and one C(2) atom to form a mixture of distorted corner, edge, and face-sharing ONa3EuC trigonal bipyramids. In the fifth O site, O(2) is bonded to one Na(1), one Na(2), one Na(3), one Eu(1), and one C(2) atom to form a mixture of distorted corner, edge, and face-sharing ONa3EuC trigonal bipyramids.
