Californium(III) fluoride is a binary
inorganic compound
In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemist ...

Physical properties
Californium(III) fluoride is a yellow-green solid and has two crystalline structures that are temperature dependent. At low temperatures the orthorhombic structure ( type) is found with
lattice constant
A lattice constant or lattice parameter is one of the physical dimensions and angles that determine the geometry of the unit cells in a crystal lattice, and is proportional to the distance between atoms in the crystal. A simple cubic crystal has o ...
s ''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.
