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