Mixed ligand complexes of alkaline earth metals: Part XII. Mg(II), Ca(II), Sr(II) and Ba(II) complexes with 5-chlorosalicylaldehyde and salicylaldehyde or hydroxyaromatic ketones

Abstract

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.
