摘要：
Four new complexes [Cu(H(2)biim)(2)(H(2)O)](NO(3))(2) (1), [Cu(H(2)biim)(2)](ClO(4))(2)center dot 2DMSO (2), [Cu(H(2)biim)(2)] [I(0.36)center dot(NO(3))(0.64)](2) (3) and {[Cu(H(2)biim)(2)(H(2)O)](SiF(6))}center dot H(2)O (4) (H(2)biim = 2,2'-biimdazole, DMSO = dimethyl sulfoxide) have been synthesized and characterized by X-ray diffraction. The different inorganic anions NO(3)(-), ClO(4)(-), [I(0.36)center dot(NO(3))(0.64)](-) and SiF(6)(2-) 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(NO(3))(0.64)](-) ions as guests in the cavity. Compound 4 was obtained by the reaction of Cu(BF(4))(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 SiF(6)(2-) in complex 4. (C) 2009 Elsevier Ltd. All rights reserved.
