Californium is a synthetic chemical element; it has symbol Cf and atomic number 98. It was first synthesized in 1950 at Lawrence Berkeley National Laboratory (then the University of California Radiation Laboratory) by bombarding curium with alpha particles ( helium-4 ions).
Californium(II) iodide (CfI 2) is a deep purple solid with a stable rhombohedral structure at room temperature and an unstable hexagonal structure. Californium(III) iodide (CfI 3) is a lemon-yellow solid that has a rhombohedral structure and sublimes at ~800 °C. [12]
Californium(III) chloride is an inorganic compound with a chemical formula CfCl 3. As in californium(III) oxide (Cf 2 O 3 ) and other californium halides, including californium(III) fluoride (CfF 3 ) and iodide (CfI 3 ), the californium atom has an oxidation state of +3.

Californium(III) bromide is shown to crystallize in both the AlCl 3 and FeCl 3 type structures. In the former structure, the californium ion is six coordinated and the three independent Cf-Br bond lengths are 279.5±0.9 pm, 282.7±1.1 pm, and 282.8±0.8 pm. [1]
This gradual transformation is an important consideration when studying the properties of elemental berkelium and its chemical compounds, since the formation of californium brings not only chemical contamination, but also free-radical effects and self-heating from the emitted alpha particles.
