Abstract In the present work we explored the coordination ability of three different ligands in Nickel, Cobalt, Cooper and Zinc chemistry. In total, seven new complexes were synthesized and characterized; three cubanes, one dimer, one heptamer and two polymer complexes. These complexes were characterized by IR and pXRD measurements, single-crystal X-ray crystallography and dc magnetic susceptibility measurements under an applied dc field of 1000 G in the temperature range 5 – 300 K. Complexes 1-7 were synthesized either under solvothermal conditions, either under room temperature. Furthermore complexes 1, 2, 3 contain Ni, Co and Cu ions respectively, while complexes 4, 5, 6, 7 contain Zn ions. For all 1, 3, 4 complexes the metallic core describes a cubane {Μ4Ο4} structure. Direct current magnetic susceptibility studies were performed on polycrystalline samples of 1 and 3 showing the presence of dominant ferromagnetic interactions between the metals for both complexes.
