Di-µ-chloro-tetrakis(ethylene)dirhodium reacts with an excess of dimethylaminodifluorophosphine at room temperature affording the monomeric complex RhCl(PF2NMe2)3. When [RhCl(C2H4)2]2 and Me2NPF2 react in a 1 : 4 molar ratio the product is the dimeric complex [RhCl(PF2NMe2)2]2. Both complexes exist as discrete entities in solution, and addition of PF2NMe2 to [RhCl(PF2NMe2)2]2 quantitatively affords RhCl(PF2NMe2)3.
