Treatment of the chelated palladium(II) complex, trans-[Pd(K 2 -Sac-CH 2 O) 2 ].2H 2 O with one mole equivalent of the diammines (L-L), L-L = 2,2'-bipyridine (bipy), ethylene diamine (en), 1,10-phenanthroline (phen), or N,N-dimethyl ethylene diammine (dmen) in EtOH solvent afforded mixed ligand complexes of the type [Pd(K 1 -Sac-CH 2 O) 2 (L-L)] in 82-93% yield. While treatment of trans-[Pd(K 2 -Sac-CH 2 O) 2 ] .2H 2 O with two mole equivalents of the monoamines (L), L=pyridine (py),
