The crystal structure described by Ba2GeO4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Ba site, Ba(2) is bonded in a 9-coordinate geometry to one O(1), two equivalent O(2), three equivalent O(3), and three 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 4-coordinate geometry to one Ba(2), two equivalent Ba(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), and one Ge(1) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to two equivalent Ba(1), three equivalent Ba(2), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to two equivalent Ba(1), three equivalent Ba(2), and one Ge(1) atom. is represented by the CIF card [CIF]
