Abstract

The synthesis of the new polynucleating ligand 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)-benzene (H4444444L) is reported along with the preparation, structure and properties of its dinuclear complexes [Cu2(H2L)2(py)2] (1), [Ni2(H2L)2(py)4] (2), [Mn2(H2L)2(dmf)4] (3), [Co2(H2L)2(dmf)4] (4) and [Co2(H2L)2(MeOH)4] (5), respectively. In complexes 1 to 5, the polydentate ligand is in its bis-deprotonated form, chelating the metals through its β-diketonate moieties. Magnetic measurements show that the metals within these molecules are maintained almost mutually independent.
