Binuclear Complexes of Class A Metal with o-Hydroxy-bis-Benzene-azo-Resorcinol

Abstract

A series of bi-nuclear mixed ligand complexes of class A metal
salts of different organic acids with o-hydroxy-bis-bezene-azo-resorcinol
have been synthesised of the general formula (ML)₂-OH-BAR,
where M = Na and K; L = deprotonated organic acids;
1-nitroso-2-naphthol, 8-hydroxy quinoline, o-nitro-phenol, 2-
hydroxy-3-naphthoic acid, anthranilic acid and OH-BAR = 0-
hydroxy-bis-benzene-azo-resorcinol. On the basis of analytical
results and IR spectra these complexes have been characterised.
