Californium(III) polyborate

Californium polyborate is a covalent compound with formula Cf[B6O8(OH)5]. In this compound the californium is in a +3 oxidation state. Californium polyborate is unusual in that californium is covalently bound to the borate. Californium was expected to resemble lanthanide elements in being highly ionic. The anion is polarisable and flexible. The 5f, 6d, 7s, and 7p orbitals of californium are all involved on the bonding. Most valence electrons are in the 5f orbital, and a significant fraction (2⁄3) in the 6d orbital, and smaller fractions of one electron are in the 7s and 7p orbitals.
