Sr2BeLaO5 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent O(2), two equivalent O(3), two equivalent O(4), and three equivalent O(1) atoms. Be(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. La(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), two equivalent O(4), and four equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded to four equivalent Sr(1) and two equivalent La(1) atoms to form distorted corner-sharing OSr4La2 octahedra. The corner-sharing octahedral tilt angles range from 34-44°. In the second O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Sr(1), one Be(1), and two equivalent La(1) atoms. In the third O site, O(2) is bonded in a distorted single-bond geometry to four equivalent Sr(1), one Be(1), and one La(1) atom. 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 La(1) atom.
