Na2Be2O3 crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded in a 4-coordinate geometry to one O(1) and three equivalent O(2) atoms. Be(1) is bonded in a distorted trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to two equivalent Na(1) and two equivalent Be(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Na(1) and two equivalent Be(1) atoms.
