Synthesis and Structure of a One-Dimensional Fe(II),Coordination Polymer Based on 1,10-Phenanthroline Derivative and 1,2,4,5-Benzenetetracarboxylate

A complex [Fe2L2(btc)(H2O)2]n(btc=1,2,4,5-benzenetetracarboxylate and L=(2-(2-chloro-6-fluorophenyl)-1H-imidazophenanthroline) was synthesized by hydrothermal reaction and characterized by elemental analysis,IR,thermogravimetric analysis(TGA),and X-ray single crystal diffraction.The title complex crystallizes in triclinic with space group P1,a=0.756 11(5) nm,b=1.003 63(4) nm,c=1.482 79(9) nm,α=91.190(1)°,β=100.569(2)°,γ=106.966(1)°,V=1.054 68(10) nm3,Z=2,R=0.035 0,wR=0.094 5.The structure analysis shows that the complex exhibits a one-dimensional chain structure.The 2D supramolecular network is constructed through π-π interactions among neighboring chains.The 2D supramolecular network was further stabilized by the hydrogen bonds.
