Berkelium(III) chloride also known as berkelium trichloride, is a chemical compound with the formula BkCl3. It is a water-soluble green salt with a melting point of 603 °C. This compound forms the hexahydrate, BkCl3·6H2O.

Preparation and reactions

This compound was first prepared in 1970 by reacting hydrogen chloride gas and berkelium(IV) oxide or berkelium(III) oxide at 520 °C:[2]

Bk2O3 + 6HCl → 2BkCl3 + 3H2O

Berkelium(III) chloride reacts with beryllocene to produce berkelocene(Bk(C5H5)3).[3] It also reacts with oxalic acid to produce berkelium oxalate. This reaction is used to purify this compound, by reacting the oxalate with hydrochloric acid.[4]

Structure

Anhydrous berkelium(III) chloride has a hexagonal crystal structure, is isostructural to uranium trichloride, and has the person symbol hP6. When heated it its melting point, it converts to an orthorhombic phase.[2] However, the hexahydrate has a monoclinic crystal structure and is isostructural to americium trichloride hexahydrate with the lattice constants a = 966 pm, b = 654 pm and c = 797 pm.[5] This hexahydrate consists of BkCl2(OH2)6+ ions and Cl− ions.

Complexes

Caesium sodium berkelium chloride is known with the formula Cs2NaBkCl6 and is produced by the reaction of berkelium(III) hydroxide, hydrochloric acid, and caesium chloride.[6]
