Syntheses, Crystal Structures, and Fluorescence Properties of Three Coordination Polymers Constructed Based on Benzoic Acid and Its Derivatives 后印本

摘要: Three new different dimensional coordination polymers, namely, [Zn(BA-)2(4,4΄-bib)1.5]n (1), [Zn(4-BrBA-)2(1,4-bmb)]n (2) and [Mn(4-BrBA-)2(4,4΄-bib)]n (3) have been assembled through the mixed-ligand synthetic strategy (4-HBrBA = 4-bromobenzoic acid, HBA = benzoic acid, 1,4-bmb = 1,4-bis(1H-imidazol-4-yl)benzene, 4,4΄-bib = 4,4΄-bis(imidazolyl)biphenyl). Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses (EA), powder X-ray diffraction (PXRD), and thermogravimetric (TG) analyses. Single-crystal X-ray diffraction analysis reveals that the crystals of complexes 1～3 are all in triclinic systems, space group P. Complexes 1 and 2 are 0D binuclear structures, and 3 is a 1D chain. Moreover, the solid state fluorescence properties of 1 and 2 have been investigated
