The compound described by MgTi(GeO3)2 crystallizes in the monoclinic C2/c space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Ti(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form TiO6 octahedra that share corners with six equivalent Ge(1)O4 trigonal pyramids and edges with two equivalent Ti(1)O6 octahedra. Ge(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form GeO4 trigonal pyramids that share corners with three equivalent Ti(1)O6 octahedra and corners with two equivalent Ge(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 45-67°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Mg(1), one Ti(1), and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), two equivalent Ti(1), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
