Rhodium carbonyl cluster chemistry. Synthesis and chemical characterization of the anion [Rh6(CO)14]4−

Abstract The anion [Rh 6 (CO) 14 ] 4− has been isolated from the reaction of [Rh 6 (CO) 16 ] with alkali hydroxides in aqueous solution. It shows high reactivity towards electrophiles and in redox condensations with other rhodium clusters; and is rapidly decomposed by carbon monoxide.
