Mixed Ligand Complexes of Alkali Metal salts of Some Organic Acids with Picolinic Acid

Abstract

The mixed ligand complexes of the general formula ML·HL'
where M = Li, Na or K, L = deprotonated 2,4-dinitrophenol, 2,4,6-
trinitrophenol, o-nitronaphthol, 2,4-dinitronaphthol and HL' =
picolinic acid, have been synthesised and characterised by physical
methods. IR spectral data show that hydrogen bonding in these
complexes are dominant factors for their stability.
