The crystal structure described by Sr3GeO5 crystallizes in the tetragonal I4cm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 10-coordinate geometry to two equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Ge(1) is bonded in a tetrahedral geometry to two equivalent O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1) and four equivalent Sr(2) atoms to form corner-sharing OSr6 octahedra. The corner-sharing octahedral tilt angles range from 0-31°. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), and one Ge(1) atom. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), and one Ge(1) atom. is represented by the CIF card [CIF]
