The material structure described by Cs4GeO4 crystallizes in the monoclinic P2_1/c space group. There are four inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 7-coordinate geometry to one O(3), one O(4), two equivalent O(2), and three equivalent O(1) atoms. In the second Cs site, Cs(2) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(4), and two equivalent O(1) atoms. In the third Cs site, Cs(3) is bonded in a 4-coordinate geometry to one O(2), one O(3), and two equivalent O(4) atoms. In the fourth Cs site, Cs(4) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(3), and two equivalent O(4) atoms. Ge(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Cs(2), three equivalent Cs(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to one Cs(2), one Cs(3), one Cs(4), two equivalent Cs(1), and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Cs(1), one Cs(2), one Cs(3), two equivalent Cs(4), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to one Cs(1), one Cs(2), two equivalent Cs(3), two equivalent Cs(4), and one Ge(1) atom. is represented by the CIF file [CIF]
