Californium(III) fluoride is a binary inorganic compound of californium and fluorine with the formula CfF
3

Physical properties

Californium(III) fluoride is a yellow-green solid[1] and has two crystalline structures that are temperature dependent. At low temperatures the orthorhombic structure (YF
3
type) is found with: a = 665.3(3) pm , b = 703.9(1) pm and c = 439.3(3) pm. At higher temperatures it forms a trigonal system (LaF
3
type) with: a = 694.5(3) pm and c = 710.1(2) pm. Here, each californium nucleus is surrounded by nine fluorine nuclei in a distorted triply-capped trigonal-prismatic structure.[2]
