Synthesis, characterization and crystal structures of supramolecular complexes of copper(II)(2,2′-biimidazole) induced by inorganic counter anions

Four new complexes [Cu(H2biim)2(H2O)](NO3) 2 (1), [Cu(H2biim)2](ClO4)2· 2DMSO (2), [Cu(H2biim)2] [I0.36·(NO3)0.64]2 (3) and {[Cu(H2biim)2(H2O)](SiF6)} ·H2O (4) (H2biim = 2,2′-biimdazole, DMSO = dimethyl sulfoxide) have been synthesized and characterized by X-ray diffraction. The different inorganic anions NO3-, ClO4-, [I0.36·(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 [I0.36·(NO3)0.64]- ions as guests in the cavity. Compound 4 was obtained by the reaction of Cu(BF4)2 with H2biim in water in glass bottle. The robust hydrogen bond of typeV R21(7) played a key role in the formation of SiF62 - in complex 4.
