B2O3 crystallizes in the orthorhombic Cmc2_1 space group. B(1) is bonded to one O(1) and three equivalent O(2) atoms to form corner-sharing BO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent B(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent B(1) atoms.
B2O3 crystallizes in the orthorhombic Cmc2_1 space group. B(1) is bonded to one O(1) and three equivalent O(2) atoms to form corner-sharing BO4 tetrahedra. The B(1)-O(1) bond length is 1.38 Å. There is one shorter (1.50 Å) and two longer (1.51 Å) B(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent B(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent B(1) atoms.
