The title coordination polymer,[Zn (L) (1,4-BDC)]n (1) (L =2-(4-fluorophenyl)-1H-imidazo [4,5-f] [1,10] phenanthroline and 1,4-H2BDC=1,4-benzenedicarboxylic acid) has been synthesized by hydrothermal method and characterized by elemental analysis,IR and single-crystal X-ray diffraction. It crystallizes in triclinic,space group P1 with a=0.970 85(16) nm,b=1.076 98(18) nm,c=1.203 6(2) nm,α=63.894(2)°,β=69.051(2)°,γ=80.427(2)°,V= 1.055 4(3) nm3,Z=2,C27H15FN4O4Zn,Mr=543.80,Dc=1.711 g·cm-3,F(000)=552,μ(Mo Kα)=1.220 mm-1,R=0.037 2 and wR=0.084 4. The 1,4-BDC ligands linked the Zn(Ⅱ) atoms to form a two-dimensional layer structure. The π-π stacking interactions between L ligands extended the adjacent layers into a three-dimensional supramolecular network. Finally,the N-H…O hydrogen bonds further stabilizes the structure of 1.
