Abstract
Synthesis and characterization of new complexes derived from the interaction of 2,4-dinitrosoresorcinol (DNR) and 6-(o-substituted phenylazo)-2,4-dinitrosoresorcinol (X = -H, -OH, -COOH) with metal [Cr(III), Fe(III), Co(II), Ni(II) and Cu(II)] salts are reported. The structures of the complexes are achieved based on elemental analysis, spectral (UV, visible, and IR). The electrical conductivity of some ligands and their complexes favored their semiconducting properties. The thermodynamic parameters of thermal decompositions are evaluated.
