Description
Summary:A nematogenic Schiff's base, N,N′-di-4-(4′-pentyloxybenzoate)salicylidene-l″, 3″-diamino-2″-propanol, (abbreviated as H 2L 6), was synthesized and its structure studied by elemental analyses, mass, NMR and IR spectra. The Schiff's base behaves as a dinegative hexa/tetradentate species in its metal complexes of the general formula, [ML 6] n where M II═Mn, Co, Ni, Cu and Zn. Their structural characterizations were made by various spectroscopic techniques. ► The work reveals the synthesis and spectral Studies of some 3d metal complexes. ► The mesogenic ligand yielded the metallomesogenic Cu II complex. ► We have included the non-mesogenic Mn II, Co II, Ni II and Zn II complexes. ► The spectral studies for investigating the bonding nature of the ligand. ► Besides the physical characteristics and geometry of the complexes.
