The compound described by KB2SbO6 crystallizes in the monoclinic Cc space group. K(1) is bonded in a 10-coordinate geometry to one O(1), one O(6), two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(4), one O(5), and one O(6) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(5) atom. Sb(1) is bonded to one O(2), one O(3), one O(4), one O(6), and two equivalent O(1) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 37°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one K(1) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to two equivalent K(1), one B(2), and one Sb(1) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to two equivalent K(1), one B(2), and one Sb(1) 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 Sb(1) 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 B(2) atom. In the sixth O site, O(6) is bonded in a 2-coordinate geometry to one K(1), one B(1), and one Sb(1) atom. is represented by the CIF file [CIF]
