摘要 Four new complexes of [Cu(bpm)(ox)(H2O)] (1), [Cu(tpd)(dca)(H2O)] (2), [Cu(bppz)(N3)2] (3), and [Cu(bpm)2(m1,3-N3)(N3)] (4) (bpm = 2,2￠-bipyrimidine, bppz = 2,3-bis(2-pyridyl)pyrazine, tpd = 4-terpyridone, dca = dicyanamide, ox = oxalate) have been prepared and characterized by X-ray single-crystal analysis and variable-temperature magnetic measurements. Compounds 1-4 are essentially mononuclear Cu(II) complexes. However, in complex 1, Cu(II) it was found that intermolecular hydrogen bonding through between H2O and ox formed 1-D chain structure. In complex 2 it was found that the hydrogen bonding between H2O and tpd of the next molecule led to for a binuclear Cu(II) complex. In complex 3, two nitrogen atoms, one of the pyridyl group of bppz and one of N3- ligands, are weakly coordinated to neighbor Cu(II) ion thus leading to formation of a 1-D chain structure. In complex 4, one nitrogen atom of terminated N3- is weakly coordinated to the neighbor Cu(II) site to form a 1-D polymeric structure. The magnetic susceptibility measurements indicate that complex 1and 4 exhibit a weak antiferromagnetic interaction whereas a ferromagnetic coupling has been established for complexes 2 and 3.
