Employing different benzendicarboxylic acids as co-ligands, two new compounds, [Cu-2(bpad)(2)(Hp)(2)](n) (1) and [Cu-2(bpad)(2)(Hip)(2)](n) (2) (Hbpad = N-3-benzoylpyridine-2-carboxamidrazone, H(2)p = phthalic acid, H(2)ip = isophthalic acid), have been synthesized. The structures and magnetic properties of title compounds have been systematically characterized. The two dinuclear Cu(II) compounds are isomers in which the metal ions adopt distinguishably penta-coordinated geometries. Cu(II) ions with square pyramidal structure are bridged by carboxylate oxygen atoms in 1, while the Cu(II) centers with trigonal bipyramid model are linked by carbamoyl oxygen atoms in 2. Magnetic measurements illustrate that the short contacts causing antiferromagnetic intra-dimer interactions consist in compound 1, whereas ferromagnetic intra-dimer interactions are performed on compound 2.
