✦ Synopsis
Three new zinc coordination polymers [Zn 2 (btc)
bipyridine) were obtained by the diffusion method and their crystal structures were determined by single-crystal X-ray diffraction. Compounds 1-3 have the similar tetrametallic unit [Zn 4 (btc) 2 ] SBUs and these SBUs are further connected into stair-like structure, 2-D layer and 3-D framework for 1, 2 and 3, in which the btc 3À ligands adopt m 3 , m 4 and m 5 coordination modes, respectively. The title compounds show strong blue fluorescence, which may be assigned as p*-n transition of the ligand mixed with the ligand-to-metal change transfer (LMCT), indicating the fluorescence, indicates the title compounds may be good candidates for blue-light photoactive materials.
