Abstract
Two new coordination polymers, [Zn(bpndc)(4,4â²-bpy)1.5]n·0.5n(4,4â²-bpy)·0.5nH2O (1) and [Zn(bpndc)(phen)(H2O)]n (2) (H2bpndc=benzophenone-4,4â²-dicarboxylic acid; 4,4â²-bpy=4,4â²-bipyridine; phen=1,10-phenanthroline) were synthesized by the hydrothermal reactions and characterized by single crystal X-ray diffraction, elemental analysis, IR spectrum and thermal analysis. In 1, 4,4â²-bpy molecules link Zn(II) ions into one-dimensional ladders, and these ladders are bridged by bpndc2â ligands, resulting in an infinite two-dimensional rhombohedral network. Such rhombohedral grids interweave each other, forming a three-dimensional structure. In 2, Zn2O2 cores are interconnected by bpndc2â ligands to generate a one-dimensional centripede-like double-chain structure, and further assembled by O-Hâ¯O hydrogen bonds and Ï-Ï stacking interactions to form three-dimensional supramolecular network with one-dimensional channels.
