Curium(III) chloride
Curium chloride is the chemical compound with the formula CmCl3.
Structure
Curium chloride has a 9 coordinate Tricapped [trigonal prismatic molecular geometry|tricapped trigonal prismatic geometry].Synthesis
Curium chloride can be obtained from the reaction of hydrogen chloride gas with curium dioxide, curium(III) oxide, or curium(III) oxychloride at a temperature of 400-600 °C:It can also be obtained from the dissolution of metallic curium in dilute hydrochloric acid:
This method is complicated by the ongoing processes of hydrolysis and hydration of the resulting compound in an aqueous solution, making it problematic to obtain a pure product.
It can be obtained from the reaction of curium nitride with cadmium chloride:
