Ammonium Pentachlor-rhodite, (NH₄)₂RhCl₅

Ammonium Pentachlor-rhodite, (NH₄)₂RhCl₅, associated with two molecules of water, was stated by Claus to result on boiling a solution of ammonium herachlor-rhodite. The monohydrated salt is prepared by concentrating a mixed solution of rhodium chloride and ammonium chloride in the theoretical quantities. It separates out in dark red crystals.
