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

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.
