The crystal structure described by BeEuSm2O5 crystallizes in the monoclinic P2_1/c space group. Be(1) is bonded in a tetrahedral geometry to one O(1), one O(3), one O(4), and one O(5) atom. Eu(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(5), and three equivalent O(3) atoms. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 8-coordinate geometry to one O(1), one O(5), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Sm site, Sm(2) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(5), and three equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Be(1), two equivalent Eu(1), one Sm(1), and two equivalent Sm(2) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Eu(1), two equivalent Sm(1), and two equivalent Sm(2) atoms. In the third O site, O(3) is bonded in a 1-coordinate geometry to one Be(1), three equivalent Eu(1), and two equivalent Sm(1) atoms. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to one Be(1), two equivalent Sm(1), and three equivalent Sm(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 Sm(1), and two equivalent Sm(2) atoms. is represented by the CIF card [CIF]
