SrGeO3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form distorted SrO8 hexagonal bipyramids that share corners with two equivalent Ge(2)O4 tetrahedra, edges with two equivalent Ge(1)O4 tetrahedra, and edges with two equivalent Ge(2)O4 tetrahedra. In the second Sr site, Sr(2) is bonded in a distorted body-centered cubic geometry to one O(1), one O(3), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms.
