SrBe3O4 crystallizes in the hexagonal P-62c space group. Sr(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. In the second Be site, Be(2) is bonded to one O(2) and three equivalent O(1) atoms to form corner-sharing BeO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Sr(1), one Be(1), and two equivalent Be(2) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to three equivalent Sr(1) and two equivalent Be(2) atoms.
