Two CuII complexes with di-2-pyridylamine (dpa) and combined bridging ligands (azide or oxalato anions), [Cu(dpa)2(N3)2]·2H2O (1) and [Cu2(mu-ox)(dpa)2(CH3CN)2](ClO 4)2 (2), have been synthesized and characterized by IR spectra, elemental analyses, TGA, UV-Vis spectra and ESR technique. The crystal structures of both complexes have been determined by single crystal X-ray diffraction analyses. In the mononuclear complex 1, the CuII center is coordinated to four N atoms of dpa and two N donors of azide (CuN6), taking an elongated octahedral geometry. The solvent water molecules interlink the neutral [Cu(dpa)2(N3)2] units through hydrogen bonds to form a two-dimensional (2D) layered structure with strong pi-pi stacking interactions between the adjacent pyridine rings. Complex 2 is made up of centro-symmetric dinuclear [Cu2(mu-ox)(dpa)2(CH3CN)2] 2+ cation and non-coordinated perchlorate anions, assembling into a one-dimensional (1D) ladder structure through hydrogen bonding with pi-pi stacking co-effect. The magnetic properties of 2 have been investigated by variable-temperature magnetic susceptibility and magnetization measurements, indicating a very strong anti-ferromagnetic coupling between the intra-molecular CuII centers (having the perfect square-pyramidal geometry) with J=-382 cm-1. The strength of the exchange interaction is discussed in detail on the basis of the structural feature.
