摘要 Two new complexes [Zn(nph)(bix)]n·nH2O (1) and [Zn(nba)2(bix)]n (2) (H2nph = 4-nitrophthalic acid, Hnba = 4-nitrobenzoic acid, bix = 1,4-bis(imidazol-1-yl)-benzene) have been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, fluorescence spectrum, single-crystal and power X-ray diffraction. Complex 1 exhibits a three-dimensional (3D) framework, which is stabilized through C–H···O hydrogen bonds and π-π stacking interactions. Complex 2 shows a zero-dimensional structure, which is further extended into a three-dimensional supramolecular structure through C–H···O and C–H···N hydrogen bonding interactions.

Abstract：Two new complexes [Zn(nph)(bix)]n·nH2O (1) and [Zn(nba)2(bix)]n (2) (H2nph = 4-nitrophthalic acid, Hnba = 4-nitrobenzoic acid, bix = 1,4-bis(imidazol-1-yl)-benzene) have been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, fluorescence spectrum, single-crystal and power X-ray diffraction. Complex 1 exhibits a three-dimensional (3D) framework, which is stabilized through C–H···O hydrogen bonds and π-π stacking interactions. Complex 2 shows a zero-dimensional structure, which is further extended into a three-dimensional supramolecular structure through C–H···O and C–H···N hydrogen bonding interactions.
