CrGa(BiO3)2 is Ilmenite-derived structured and crystallizes in the trigonal R3 space group. Cr(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form CrO6 octahedra that share corners with six equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles are 25°. Ga(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form GaO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 25°. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Cr(1), one Ga(1), one Bi(1), and one Bi(2) atom. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Cr(1), one Ga(1), one Bi(1), and one Bi(2) atom.
