Synthesis and Characterization of New Complexes Derived from 4-(4- (Dimethylamino)Phenyl)-2-Oxo6-(2-Oxo-6-(Phenyldiazenyl)-2H-Chromen-3-Yl)-1,2- Dihydropyridine -3-Carbonitrile with Manganese (II), Iron (II), Cobalt (II), and Nickel (II) Ions


This work involves the chemical synthesis of a series of metalcomplexes have been the general production (M(L)2X2), where M = Mn(II),Fe(II), Co(II), Ni(II) and Cu(II).The ligand (L): 4-(4-(dimethylamino) phenyl)-2-oxo-6-(2-oxo-6-(phenyldiazenyl)-2H-chromen-3-yl)-1,2-dihydropyridine-3-carbonitrile (DPOPCD). These complexes have been prepared and characterizedby ligand to metal mole ratio, molar conductance, and spectral (Uv-Visible andFT-IR) studies. The IR spectral data propose the involvement from oxygen andnitrogen at coordination for the central metal ion. On the resulting products, anoctahedral geometry has suggested to all complexes.
