Synthesis, spectroscopic characterization and magnetic properties of homo- and heterodinuclear complexes of transition and non-transition metal ions with a new Schiff base ligand

Four homodinuclear complexes of Ni(II)–Ni(II), Cu(II)–Cu(II), Co(II)–Co(II) and Co(III)–Co(II) and five heterodinuclear complexes of Co(III)–Zn(II), Co(III)–Cu(II), Co(III)–Ni(II), Cu(II)–Zn(II) and Zn(II)–Cu(II) with the octadentate Schiff base compartmental ligand 1,8-N-bis(3-carboxy)disalicylidene-3,6-diazaoctane-1,8-diamine (H4fsatrien) have been synthesized. The complexes have been characterized with the help of elemental analyses, molecular weights, molar conductances, magnetic susceptibilities and spectroscopic (UV–vis, IR, ESR) data. Cryomagnetic data also helped to elucidate the structural features of the Cu(II) complexes.
