In the fourth Fe2+ site, Fe2+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of Fe–O bond distances ranging from 1.88–1.94 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+, four K1+, and one Fe2+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+, three K1+, and one Fe2+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+, three K1+, and one Fe2+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+, four K1+, and one Fe2+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+, three K1+, and one Fe2+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+, four K1+, and one Fe2+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+, four K1+, and one Fe2+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+, three K1+, and one Fe2+ atom. In the ninth O2- site, O2- is bonded in a 5-coordinate geometry to three Rb1+, one K1+, and two Fe2+ atoms. In the tenth O2- site, O2- is bonded in a 5-coordinate geometry to two Rb1+, two K1+, and two Fe2+ atoms.« less
