The material structure described by SrTiGeO5 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), two equivalent O(2), and two equivalent O(5) atoms. Ti(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form TiO6 octahedra that share corners with two equivalent Ti(1)O6 octahedra and corners with four equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 32°. Ge(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form GeO4 tetrahedra that share corners with four equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-55°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Sr(1), one Ti(1), and one Ge(1) atom. In the second O site, O(2) is bonded to two equivalent Sr(1), one Ti(1), and one Ge(1) atom to form a mixture of distorted corner and edge-sharing OSr2TiGe tetrahedra. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Sr(1), one Ti(1), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Sr(1) and two equivalent Ti(1) atoms. In the fifth O site, O(5) is bonded to two equivalent Sr(1), one Ti(1), and one Ge(1) atom to form a mixture of distorted corner and edge-sharing OSr2TiGe tetrahedra. is represented by the CIF card [CIF]
