The corner-sharing octahedra tilt angles range from 17–61°. In the fifth O2- site, O2- is bonded in a 6-coordinate geometry to four Ca2+, one Ir4+, and one Ni2+ atom. In the sixth O2- site, O2- is bonded to five Ca2+ and one Ir4+ atom to form a mixture of distorted corner, edge, and face-sharing OCa5Ir octahedra. The corner-sharing octahedra tilt angles range from 0–59°. In the seventh O2- site, O2- is bonded to five Ca2+ and one Ir4+ atom to form distorted OCa5Ir octahedra that share corners with seven OCa4NiIr octahedra and faces with two OCa5Ir octahedra.
