文摘
Three new metal-organic coordination polymers, Cd(bpdc)(phen)2·2H2O (1) (H2bpdc = biphenyl-4,4'-dicarboxylic acid), Cd(BDC)(phen)·DMF (2) (H2BDC = benzene-1,4-dicarboxylic acid), and Cd2(btec)(phen)2(H2O)2(3) (H4btec = 1,2,4,5-benzenetetracarboxylic acid), were synthesized under different conditions by using the metal-organic coordination compound Cd(phen)2(NO3)2 as the metal source instead of inorganic metal salt. Polymer 1 isa 1-D zigzag chain, which crystallizes in the monoclinic system, Cc space group. Polymer 2 is a 2-D layered network,which crystallizes in the monoclinic system, P2/c space group. The 3-D supramolecular framework 3 crystallizes inthe triclinic system, P
space group. The particular interest of 3 is two entirely independent cadmium atoms in itsstructure. They separately form 1-D polymeric chains, which are alternately arranged to form a 3-D supramolecularframework through interchain hydrogen bonds. Additionally, these three compounds show strong fluorescence inthe solid state at room temperature.
