Synthesis, Crystal Structure, and Fluorescent Properties of a 2D Zinc(II) Complex

The 2,2-biphenyl-4,4-dicarboxylate (H(2)bpy-4,4-dc) and 2,2-Bis(imidazol-1-ylmethyl)-biphenyl (bipb) have been selected as the bridging ligands. One zinc(II) MOF, [Zn(bpy-4,4-dc)(bipb)](n) has been successfully obtained by hydrothermal reaction and synthesis. The molecular structure has been elucidated by single-crystal X-ray diffraction. The complex possesses of 1D block chain [(bpy-4,4-dc)(2)(bibp)(2)Zn-4]. Taking advantage of the tetrahedral coordination preference of the Zn metal centers, the connected chains adopt a folding conformation to form a two-dimensional architecture. The complex was further characterized by IR spectroscopy, PXRD pattern, fluorescent spectra, and thermal stability measurements.
