The material structure described by Sr2BeSmO5 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(3), two equivalent O(4), and three equivalent O(2) atoms. Be(1) is bonded in a tetrahedral geometry to one O(3), one O(4), and two equivalent O(2) atoms. Sm(1) is bonded in a 8-coordinate geometry to one O(3), one O(4), two equivalent O(1), and four equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one Be(1), and one Sm(1) atom. In the second O site, O(1) is bonded in a 6-coordinate geometry to four equivalent Sr(1) and two equivalent Sm(1) atoms. In the third O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Sr(1), one Be(1), and two equivalent Sm(1) atoms. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to four equivalent Sr(1), one Be(1), and one Sm(1) atom. is represented by the CIF file [CIF]
