摘要
Rhodium(III) and ruthenium(II) complexes supported by a pentadentate tetrapodal (pentaPod) phosphine ligand are synthesized through abstraction of one chloride ligand from initially obtained kappa(4)-pentaPod coordinated dichloro complexes [MCl2(kappa(4)-(P2PP2Ph)-P-Me)](+/0) (M=Rh(III), Ru(II)) with alkali salts of weakly coordinating anions. While for the rhodium kappa(5)-pentaPod complex the remaining, axial chloride ligand could not be replaced by di- or triatomic ligands, in case of ruthenium the complexes [Ru(CN)(kappa(5)-(P2PP2Ph)-P-Me]Al(pftb)(4) (5) and [Ru(N-3)(kappa(5)-(P2PP2Ph)-P-Me]Al(pftb)(4) (6) could be generated through ligand exchange. By comparison of NMR parameters and employing DFT calculations, additional insights into the electronic influence of different ligands (i. e., Cl-, CN-, N-3(-)) could be gained.
