The crystal structure described by BeO2 crystallizes in the orthorhombic P2_12_12_1 space group. Be(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing BeO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Be(1) atoms. In the second O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Be(1) atoms. is represented by the CIF card [CIF]
