The crystal structure described by KBGe2O6 crystallizes in the orthorhombic P2_12_12_1 space group. K(1) is bonded in a 10-coordinate geometry to one O(2), one O(6), two equivalent O(1), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. B(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form BO4 tetrahedra that share  a cornercorner with one Ge(1)O4 tetrahedra and corners with three equivalent Ge(2)O4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one O(1), one O(6), and two equivalent O(2) atoms to form GeO4 tetrahedra that share  a cornercorner with one B(1)O4 tetrahedra,  a cornercorner with one Ge(2)O4 tetrahedra, and corners with two equivalent Ge(1)O4 tetrahedra. In the second Ge site, Ge(2) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form GeO4 tetrahedra that share  a cornercorner with one Ge(1)O4 tetrahedra and corners with three equivalent B(1)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1), 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 K(1) and two equivalent Ge(1) atoms. In the third O site, O(3) is bonded in a 2-coordinate geometry to two equivalent K(1), one B(1), and one Ge(2) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent K(1), one B(1), and one Ge(2) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1), one B(1), and one Ge(2) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one K(1), one Ge(1), and one Ge(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
