Synthesis and characterization of mixed ligand complexes of cobalt(II) with 2-hydroxy-1-naphthaldehyde and salicylaldehyde, hydroxyaromatic ketones or β-diketones

Abstract

Mixed ligand complexes of general formula [Co(L)(L')(H 2 O) 2 ] (where HL = 2-hydroxy-1-naphthaldehyde, HL' = 2-hydroxyacetophenone, 2-hydroxypropiophenone, 2-hydroxybenzophenone, pentane-2,4-dione, 1-phenylbutane-1,3-dione or 1,3-diphenylpropane-1,3-dione) have been synthesized and characterized by elemental analyses, TLC, conductances, magnetic moments, IR and electronic spectra.
