摘要
Three new different dimensional coordination polymers, namely, [Zn（BA-）2（4,4？-bib）-1.5]n（1）, [Zn（4-Br BA-）2（1,4-bmb）]n（2） and [Mn（4-Br BA）2（4,4？-bib）]n（3） have been assembled through the mixed-ligand synthetic strategy（4-HBr BA = 4-bromobenzoic acid, HBA = benzoic acid, 1,4-bmb = 1,4-bis（1 H-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 P1. Complexes 1 and 2 are 0D binuclear structures, and 3 is a 1 D chain. Moreover, the solid state fluorescence properties of 1 and 2 have been investigated.
