The structure described by Ba3Ge2(B3O8)2 crystallizes in the triclinic P-1 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(2), two equivalent O(5), two equivalent O(6), and two equivalent O(7) atoms. In the second Ba site, Ba(2) is bonded in a 11-coordinate geometry to one O(2), one O(4), one O(7), two equivalent O(1), two equivalent O(3), two equivalent O(6), and two equivalent O(8) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded to one O(1), one O(3), one O(5), and one O(8) atom to form BO4 tetrahedra that share  a cornercorner with one B(2)O4 tetrahedra and corners with two equivalent Ge(1)O4 tetrahedra. In the second B site, B(2) is bonded to one O(2), one O(4), one O(5), and one O(7) atom to form BO4 tetrahedra that share  a cornercorner with one B(1)O4 tetrahedra and corners with two equivalent Ge(1)O4 tetrahedra. In the third B site, B(3) is bonded in a trigonal planar geometry to one O(6), one O(7), and one O(8) atom. Ge(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form GeO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra and corners with two equivalent B(2)O4 tetrahedra. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Ba(2), one B(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one Ba(2), one B(2), and one Ge(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to two equivalent Ba(2), one B(1), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Ba(2), one B(2), and one Ge(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one B(1), and one B(2) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one Ba(1), two equivalent Ba(2), and one B(3) atom. In the seventh O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one Ba(2), one B(2), and one B(3) atom.
