β-Ga2O3 contains two crystallographically different Ga atoms in the asymmetric unit, one with tetrahedral and the other with octahedral coordination geometry. The Ga-O distances are in the range 1.833 (1)–1.863 (2) Å within the tetrahedra, but are longer within the octahedra [1.935 (2)–2.074 (1) Å]. The O atoms have a distorted cubic close packing. The crystal structure of β-gallium oxide has been determined previously by Geller [J. Chem. Phys. (1960). 33, 676–684].
