Synthesis and Crystal Structure of a One-Dimensional Cd(II) Coordination Polymer Based on 1,10-Phenanthroline Derivative and 1,3-Benzenedicarboxylic Acid

A new 1D chain coordination polymer,[Cd2(L)2(1,3-BDC)2]n 1(L=2-(3-fluorophenyl)-1H-imidazophenanthroline and 1,3-H2BDC=1,3-benzenedicarboxylic acid) has been hydrothermally synthesized and characterized by elemental analysis,IR and single-crystal X-ray diffraction.It crystallizes in triclinic,space group P1 with a=1.080 8(4) nm,b=1.149 5(4) nm,c=1.924 8(7) nm,α=106.482(5)°,β=99.436(6)°,γ=93.093(6)°,V=2.249 2(14) nm3,Z=4,C27H15CdFN4O4,Mr=590.83,Dc=1.745 g·cm-3,F(000)=1 176,μ(Mo Kα)=1.024 mm-1,R=0.044 5 and wR=0.111 7.In compound 1,the 1,3-BDC ligands linked the adjacent Cd(Ⅱ) atoms to generate a one-dimensional chain structure.The CH-π interactions between L and 1,3-BDC extended the adjacent chains into a two-dimensional supramolecular layer.The N-H…O hydrogen bond further stabilizes the structure of 1.CCDC: 859146.
