Treatment of the chelated palladium(II) complex, trans-[Pd(K2-Sac-CH2O)2].2H2O 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(K1-Sac-CH2O)2(L-L)] in 82-93% yield. While treatment of trans-[Pd(K2-Sac-CH2O)2].2H2O with two mole equivalents of the monoamines (L), L=pyridine (py), 3-methylpyridine (3-mpy) or 3-aminopyridine (3-apy) in EtOH solvent gave trans-[Pd(K1-Sac-CH2O)2(L)2] complexes in 86-89% yield The prepared complexes were characterized by elemental CHN analysis, .conductivity measurements,. infrared and 1H nmr spectra.

Metal Chlorides

The reactions of alkaline earth metal chlorides with 5-chlorosalicylaldehyde and salicylaldehyde, 2-hydroxyacetophenone or 2-hydroxypropiophenone have been carried out in 1: 1: 1 mole ratio and the mixed ligand complexes of the type MLL?(H2O)2 (where M = Mg(II), Ca(II), Sr(II) and Ba(II),HL= 5-chlorosalicylaldehyde and HL?= salicylaldehyde, 2-hydroxyacetophenone or 2-hydroxypropiophenone) have been isolated. These complexes were characterized by TLC, conductance measurements, IR and 1H-NMR spectra.
