3D Pb~(II)-coordination framework based on rod-shaped Pb-O-Pb SBUs defining a new (4,5)-connected net topology

摘要

A novel 3D coordination framework [Pb2(hfipbb)2(bpp)]_n (1) [H2hfipbb = 4,4'-(hexa-fluoroisopropylidene) bis(benzoic acid), bpp = 1,3-bis(4-pyridyl)propane] based on inorganic rod-shaped infinite Pb-O-Pb chain is presented, which possesses a new (4,5)-connected network topology and shows high thermal stability and strong photoluminescence at room temperature.
