A novel heterohexanuclear Schiff base complex, {[CuMnL1][CuL2]}2·2CH3OH (1) (H4L1 = N-N′-bis[(3-carboxylsalicylidene)]-N″-(2-aminoethyl)-1,2-ethanediamine and H2L2 = N-(3-carboxylsalicylidene)-N″-(2-aminoethyl)-1,2-ethanediamine) has been synthesized and characterized by elemental analysis, IR spectrum, thermogravimetric analysis (TGA), single-crystal X-ray diffraction and magnetic properties. Single-crystal structural analysis shows that complex 1 displays a rare heterohexanuclear structure. The asymmetry unit of complex 1 contains a trinuclear [CuMnL1][CuL2]moieties. The result reveals that one imine bond in the ligand H4L1 is degraded into NH2 group and that one 3-carboxylsalicylidene is thrown away, giving the new ligand H2L2. Its magnetic properties have also been investigated. The interactions between metal ions in the trinuclear moiety are all antiferromagnetic.
