Syntheses, Crystal Structures and Luminescent Properties of Lead(Ⅱ) and Cadmium(Ⅱ) Coordination Polymers Constructed from Biphenyl-2,5,3'-tricarboxylate
摘要:
Two coordination polymers, namely [Pb(Hbtc)(phen)]n (1) and {[Cd3(btc)2(H2O)4]·2H2O}n (2, H3btc=biphenyl-2,5,3'-tricarboxylic acid, phen=1,10-phenanthroline), were assembled. Single-crystal X-ray diffraction studies show that compound 1 possesses a zigzag chain 1D coordination network, which is further extended into a 3D supramolecular architecture via O-H…O hydrogen bonds and π-π packing interactions. Compound 2 features a 3D open framework based on a tricadmium(Ⅱ) subunit, generating a trinodal 4,4,6-connected net with the 4,4,6T24 topology defined by the point symbol of (44·62)3(46·69)2. Thermal stability and luminescent properties of both compounds were studied and discussed.
