[RhCl(CH2CH2)2]2 reacts with PMe3 in the presence of ethylene to give an unusual 18-electron five-coordinate Rh(I) complex, RhCl(CH2CH2)2(PMe3)2 (1). The structure of 1 was fully characterized by X-ray crystallography as well as 1H and 31P NMR. The bis(ethylene) adduct (1) is isolable but in equilibrium with the corresponding mono(ethylene) complex RhCl(CH2CH2)(PMe3)2 (2) in solution.
