Abstract: New cationic trialkylphosphines [P(CH2NH2R){CH2N(R)CH2N(R)CH2}]+ (R ) C6H5CH2, a; 4-FC6H4CH2, b), as their Cl- (1a, 1b), SbF6 - (2a, 2b), and PF6 - (3a, 3b) salts, are described. The phosphine framework is conformationally locked, in the solid state, through pairs of intramolecular N-H · · · N hydrogen bonds which are maintained in the RuII and RhIII complexes 4 and 5. Phosphines 1a-3b can be considered as charged variants of the well-known PTA ligand.
