MnFeGaO4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with six equivalent Fe(1)O6 octahedra and corners with six equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 58-60°. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra, edges with two equivalent Fe(1)O6 octahedra, and edges with four equivalent Ga(1)O6 octahedra. Ga(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form GaO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra, edges with two equivalent Ga(1)O6 octahedra, and edges with four equivalent Fe(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Mn(1), two equivalent Fe(1), and one Ga(1) atom to form distorted OMnGaFe2 trigonal pyramids that share corners with six equivalent O(2)MnGa2Fe trigonal pyramids, corners with six equivalent O(1)MnGaFe2 trigonal pyramids,  an edgeedge with one O(1)MnGaFe2 trigonal pyramid, and edges with two equivalent O(2)MnGa2Fe trigonal pyramids. In the second O site, O(2) is bonded to one Mn(1), one Fe(1), and two equivalent Ga(1) atoms to form distorted OMnGa2Fe trigonal pyramids that share corners with six equivalent O(2)MnGa2Fe trigonal pyramids, corners with six equivalent O(1)MnGaFe2 trigonal pyramids,  an edgeedge with one O(2)MnGa2Fe trigonal pyramid, and edges with two equivalent O(1)MnGaFe2 trigonal pyramids.
