Synthesis and spectral studies of mixed ligand complexes of cobalt(II) with carbonyl compounds

Abstract

Complexes of the type [COLL'(H 2 O) 2 ] (where HL = salicylaldehyde, HL' = 2-hydroxyacetophenone, 2-hydroxypropiophenone; HL = 2-hydroxyacetophenone, HL' = 2-hydroxypropiophenone; HL = pentane-2,4-dione, HL' = 1-phenylbutane-1,3-dione, 1,3-diphenylpropane-1,3-dione; HL = 1-phenylbutane-1,3-dione, HL' = 1,3-diphenylpropane-1,3-dione) have been synthesized by the reactions of cobalt(II) nitrate with two different carbonyl compounds in 1: 1: 1 molar ratios. These have been characterized by elemental analyses, conductances, magnetic moments, thermal analyses and IR, electronic and FAB mass spectra.
