摘要

Four new complexes [Cu(H(2)biim)(2)(H2O)](NO3)(2) (1), [Cu(H(2)biim)(2)](ClO4)(2)center dot 2DMSO (2), [Cu(H(2)biim)(2)] [I-0.36 center dot(NO3)(0.64)](2) (3) and {[Cu(H(2)biim)(2)(H2O)](SiF6)}center dot H2O (4) (H(2)biim = 2,2'-biimdazole, DMSO = dimethyl sulfoxide) have been synthesized and characterized by X-ray diffraction. The different inorganic anions NO3-, ClO4-, [I-0.36 center dot(NO3)(0.64)](-) and SiF62- in these complexes lead to different 3D structures. Among them, complex 3 has an interesting 3D porous structure with two [I-0.36 center dot(NO3)(0.64)](-) ions as guests in the cavity. Compound 4 was obtained by the reaction of Cu(BF4)(2) with H(2)biim in water in glass bottle. The robust hydrogen bond of typeV R-2(1)(7) played a key role in the formation of SiF62- in complex 4.
