The crystal structure described by BeEuNd2O5 crystallizes in the orthorhombic Pna2_1 space group. Be(1) is bonded in a tetrahedral geometry to one O(2), one O(3), one O(4), and one O(5) atom. Eu(1) is bonded in a 9-coordinate geometry to one O(4), two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms. In the second Nd site, Nd(2) is bonded in a 9-coordinate geometry to one O(5), two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent Eu(1), two equivalent Nd(1), and two equivalent Nd(2) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Be(1), two equivalent Eu(1), one Nd(1), and two equivalent Nd(2) atoms. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Be(1), two equivalent Eu(1), one Nd(1), and two equivalent Nd(2) atoms. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to one Be(1), one Eu(1), two equivalent Nd(1), and two equivalent Nd(2) atoms. In the fifth O site, O(5) is bonded in a 1-coordinate geometry to one Be(1), two equivalent Eu(1), one Nd(2), and two equivalent Nd(1) atoms. is represented by the CIF file [CIF]
