MgTi(GaO2)4 crystallizes in the triclinic P-1 space group. Mg(1) is bonded in a distorted square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Ti(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form TiO6 octahedra that share corners with four equivalent Ga(2)O6 octahedra, corners with four equivalent Ga(1)O4 trigonal pyramids, and edges with two equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one O(2), one O(4), and two equivalent O(1) atoms to form GaO4 trigonal pyramids that share corners with two equivalent Ti(1)O6 octahedra, corners with five equivalent Ga(2)O6 octahedra, and corners with two equivalent Ga(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 53-72°. In the second Ga site, Ga(2) is bonded to one O(1), two equivalent O(3), and three equivalent O(4) atoms to form GaO6 octahedra that share corners with two equivalent Ti(1)O6 octahedra, corners with five equivalent Ga(1)O4 trigonal pyramids, and edges with four equivalent Ga(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. There are four inequivalent O sites.
