Californium(III) fluoride explained

Californium(III) fluoride is a binary inorganic compound of californium and fluorine with the formula ^[1]

Physical properties

Californium(III) fluoride is a yellow-green solid^[2] and has two crystalline structures that are temperature dependent. At low temperatures the orthorhombic structure (type) is found with lattice constants a = 665.3(3) pm, b = 703.9(1) pm and c = 439.3(3) pm. At higher temperatures it forms a trigonal system (type) with: a = 694.5(3) pm and c = 710.1(2) pm. Here, each californium atom is surrounded by nine fluorine atoms in a distorted triply-capped trigonal-prismatic structure.^{[3] [4]}
