MnGaO3 crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded to six equivalent O(2) atoms to form distorted MnO6 octahedra that share corners with six equivalent Ga(1)O5 trigonal bipyramids and edges with six equivalent Mn(1)O6 octahedra. Ga(1) is bonded to two equivalent O(2) and three equivalent O(1) atoms to form GaO5 trigonal bipyramids that share corners with six equivalent Mn(1)O6 octahedra and corners with six equivalent Ga(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 63°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to three equivalent Ga(1) atoms. In the second O site, O(2) is bonded to three equivalent Mn(1) and one Ga(1) atom to form a mixture of corner and edge-sharing OMn3Ga tetrahedra.

Mn(1) is bonded to six equivalent O(2) atoms to form distorted MnO6 octahedra that share corners with six equivalent Ga(1)O5 trigonal bipyramids and edges with six equivalent Mn(1)O6 octahedra. All Mn(1)-O(2) bond lengths are 2.11 Å. Ga(1) is bonded to two equivalent O(2) and three equivalent O(1) atoms to form GaO5 trigonal bipyramids that share corners with six equivalent Mn(1)O6 octahedra and corners with six equivalent Ga(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 63°. Both Ga(1)-O(2) bond lengths are 2.01 Å. All Ga(1)-O(1) bond lengths are 1.89 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to three equivalent Ga(1) atoms. In the second O site, O(2) is bonded to three equivalent Mn(1) and one Ga(1) atom to form a mixture of corner and edge-sharing OMn3Ga tetrahedra.
