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.
