In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to four K1+, one Nb5+, and one B3+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent K1+ and two equivalent Nb5+ atoms. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to four K1+, one Nb5+, and one B3+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to three K1+ and two equivalent Nb5+ atoms. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to four K1+, one Nb5+, and one B3+ atom.
