Шаблон:Chembox Californium(II) iodide is a binary inorganic compound of californium and iodine with the formula Шаблон:Chem.[1]
Synthesis
It can be produced by reducing californium triiodide with hydrogen in a quartz thin tube at 570 °C:[2]
Physical properties
The compound forms a dark purple solid. At slightly higher temperatures, it melts and reacts with the silica in the thin tube, producing CfOI.Шаблон:Cn
Californium diiodide has two crystal structures, one is [[Cadmium(II) chloride|Шаблон:Chem]]-type crystal structure, stable at room temperature, with lattice parameters a = 743.4 ± 1.1 pm and α = 35.83 ± 0.07°; the other is metastable, of Шаблон:Chem-type with lattice parameters a = 455.7 ± 0.4 pm and c = 699.2 ± 0.6 pm.[3] Californium diiodide has an absorption band in the wavelength range from 300 to 1100 nm, which proves the existence of Cf(II).[4]
