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 electricalconductivity of some ligands and their

Abstract Hydrated Ni(II) chloride reacts with new substituted phenylazo-2,4-dinitrosoresorcinol ligands to give complexes with stoichiometry [NiClnL(H2O)](n = 0 or 1, and L is the anion of the ligand). These complexes have room-temperature μcff in the 1.77–2.66BM/Ni range. The planar ⇌ tetrahedral equilibrium for these complexes is proved by electronic spectral studies either in a Nujol mull or in
