GaAsO4 crystallizes in the trigonal P3_121 space group. Ga(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form GaO4 tetrahedra that share corners with four equivalent As(1)O4 tetrahedra. As(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form AsO4 tetrahedra that share corners with four equivalent Ga(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(2) is bonded in a bent 120 degrees geometry to one Ga(1) and one As(1) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Ga(1) and one As(1) atom.
