BiGaO3 crystallizes in the orthorhombic Pcca space group. Ga(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing GaO4 tetrahedra. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ga(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ga(1) and two equivalent Bi(1) atoms.
BiGaO3 crystallizes in the orthorhombic Pcca space group. Ga(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing GaO4 tetrahedra. Both Ga(1)-O(1) bond lengths are 1.85 Å. Both Ga(1)-O(2) bond lengths are 1.88 Å. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Bi(1)-O(2) bond lengths are 2.67 Å. There are two shorter (2.19 Å) and two longer (2.30 Å) Bi(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ga(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ga(1) and two equivalent Bi(1) atoms.
