摘要

A novel two-dimensional (2D) Zn II coordination framework, poly[[mu-1,3-bis(2-methyl-1H-imidazol-1-yl)benzene](mu-5-nitrobenzene-1,3-dicarboxylato)zinc(II)], [Zn(C8H3NO6)(C14H14N4)](n) or [Zn(NO2-BDC)(1,3-BMIB)](n) [1,3-BMIB is 1,3bis-(2-methyl-1H-imidazol-1-yl)benzene and NO2-H2BDC is 5-nitrobenzene-1,3-dicarboxylic acid], has been prepared and characterized by IR, elemental analysis, thermal analysis and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis revealed that the compound is a new 2D polymer with a 6 3 topology parallel to the (10 (2) over bar) crystal planes based on left-handed helices, right-handed helical NO2-BDC-Zn chains and [Zn-2(1,3-BMIB)(2)](n) clusters. In the crystal, adjacent layers are further connected by C-H center dot center dot center dot O hydrogen bonds, C-H center dot center dot center dot pi interactions, C-O center dot center dot center dot pi interactions and N-O center dot center dot center dot pi interactions to form a three-dimensional structure in the solid state. In addition, the compound exhibits strong fluorescence emissions in the solid state at room temperature.
