The reaction of hydrated rhodium(III) chloride with formic acid in refluxing ethoxyethanol afforded in a convenient way the known rhodium carbonyl chlorido complex anion cis-[RhCl2(CO)2]−. This species was formed in good yield and was characterized as its PPN salt (PPN+ = bis(triphenylphosphane)iminium cation). The molecular structure of the title compound PPN[RhCl2(CO)2] was confirmed by X-ray diffraction and shown to be isomorphous to PPN[IrCl2(CO)2].
