A number of mixed ligand complexes of alkali metal salts of some organic acids with picolinic acid and quinaidinic acid have been synthesised and characterised. They have the general formula ML.HL', where, M=Li, Na or K ; L=deprotonated 8-hydr­oxyquinotine, 1-nitroso-2-naphthol or o-nitrophenol, and HL' = picolinic acid or quinal­dinic acid. Their it spectra suggest the coordination of the alkali metals through oxygen atom of the COOH group as well as nitrogen atom of the heterocyclic ring.
