This article describes some complexes of Cu(II) and Co(II with NN′-bis-8-quinolylethylenediamine ligand (nn′). All the compounds are of stoichiometry [MX2(nn′)] (M = Cu or Co; X = Cl-, Br-, I-, NO-3 or SCN-). The electronic spectra are consistent with distorted octahedral geometry around the ions, indicating the four coordination of the nn′ ligand. Magnetic susceptibility measurements down to 100 K show antiferromagnetic interactions in all the Cu(II) compounds demonstrating the existence of the ionic and bridging X group. Infrared spectra show the presence of ionic and bridging nitrate in the [M(NO3)2(nn′)] (M = Co or Cu) compounds and ionic and bridging NCS group in the [Cu(NCS)2(nn′)] compound. © 1984.
