A series of diastereoisomeric half-sandwich complexes with Schiff bases from salicylaldehyde and L-alpha-amino acid esters including chiral metal atoms, [(eta(5)-C5H5)(Cl)M(N,O-Schiff base)], has been obtained from chloro bridged complexes [(eta(5)-C5Me5)(Cl)M(mu-Cl)](2) (M = Rh, Ir). Abstraction of chloride from these complexes with Ag[BF4] or Ag[SO3CF3] affords the highly sensitive compounds [(eta(C5Me5)-C-5)M(N,O-Schiff base]X-+(-) (M = Rh, Ir; X = BF4, CF3SO3) to which PPh3 can be added under formation of [(eta(C5Me5)-C-5)M(PPh3)(N,O-Schiff base]X-+(-) . The diastereoisomeric ratio of the complexes (1-7 and 11-12) has been determined from NMR spectra.
