The reactions of Schiff bases from benzophenone and α-amino acid and peptide esters with tetrachloropalladate afford the chloro bridged ortho palladated complexes 1-8 and 11-18. The chloro bridges are cleaved by P and N donors (PR3, pyridine, α-amino acid ester) to give the monomeric complexes 19-35. From 1, 2, 3 and bidendate ligands (dppe, α-amino carboxylates, cysteine methyl ester) the bis(chelates) 36-41, with N-diphenylmethylene glycylglycine ester the C,N,N chelates 46 and 47 are obtained.
The complexes 14, 23 and 47 were characterized by X-ray diffraction. Due to the two neighbouring five membered chelate rings in 47 a considerable distortion from the square planar coordination is observed.
