In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Cu2+, one Zn2+, and one B3+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Cu2+, one Zn2+, and one B3+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cu2+ and one B3+ atom.
