MgTi2Mn2O6 crystallizes in the triclinic P-1 space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, edges with six equivalent Ti(1)O6 octahedra, and faces with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-45°. Ti(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TiO6 octahedra that share corners with nine equivalent Mn(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, edges with three equivalent Ti(1)O6 octahedra, and  a faceface with one Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-55°. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with three equivalent Mg(1)O6 octahedra, corners with nine equivalent Ti(1)O6 octahedra, edges with three equivalent Mn(1)O6 octahedra,  a faceface with one Mg(1)O6 octahedra, and  a faceface with one Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-55°. There are three inequivalent O sites.
