The reactions o f Schiff bases from benzophenone and a-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 (P R 3, pyridine, a-amino acid ester) to give the monomeric complexes 19 -35. From 1,2,3 and bidendate ligands (dppe, a-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.
