The structure described by BaBeNd2O5 crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and three equivalent O(4) atoms. Be(1) is bonded in a tetrahedral geometry to one O(1), one O(3), one O(4), and one O(5) atom. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 7-coordinate geometry to one O(5), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. In the second Nd site, Nd(2) is bonded in a 8-coordinate geometry to one O(1), one O(3), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms. There are five inequivalent O sites. In the first O site, O(5) is bonded in a 1-coordinate geometry to one Be(1), one Nd(1), and two equivalent Nd(2) atoms. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ba(1), one Be(1), one Nd(2), and two equivalent Nd(1) atoms. In the third O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Nd(1), and two equivalent Nd(2) atoms. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Ba(1), one Be(1), one Nd(2), and two equivalent Nd(1) atoms. In the fifth O site, O(4) is bonded in a distorted single-bond geometry to three equivalent Ba(1), one Be(1), and two equivalent Nd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
