The structure described by SrBeSm2O5 crystallizes in the orthorhombic Pna2_1 space group. Sr(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. 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 Sm sites. In the first Sm site, Sm(1) 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. In the second Sm site, Sm(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 distorted single-bond geometry to two equivalent Sr(1), one Be(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 Sr(1), two equivalent Sm(1), and two equivalent Sm(2) atoms. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent Sr(1), one Be(1), one Sm(1), and two equivalent Sm(2) atoms. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to one Sr(1), one Be(1), two equivalent Sm(1), and two equivalent Sm(2) atoms. In the fifth O site, O(5) is bonded in a 1-coordinate geometry to two equivalent Sr(1), one Be(1), one Sm(2), and two equivalent Sm(1) atoms. is represented by the CIF file [CIF]
