The compound described by B2O3 crystallizes in the trigonal P3_121 space group. B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. 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 B(1) atoms. In the second O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent B(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
