【 摘 要 】

A new Cu(II) complexes containing nitroxide radicals Cu(NITpPy)2[Cu(CN)3]. 2CH3OH.2H2O has been successfully synthesized. The single crystal X-ray analysis revealed that the compound belongs to monoclinic crystal system (C2/c (#15)). The existence of the C≡N radical and water molecules are observed by using infra-red within the range of 4000-500 cm-1and 3500-3000 cm-1, respectively. The Cu(NITpPy)22+units are connected through N(CN)2-bridging ligands in 2 coordination developing, respectively, into one-dimensional and two-dimensional polymeric networks. Paramagnetic interactions in the compound appear in the vicinity of room temperature. As the temperature decreased, low dimensional antiferromagnetic interactions established and Cu(II)-radicals antiferromagnetic interactions dominates down to 2 K with μeff= 0.8129 μB
