一个二维锰配位聚合物[Mn2(L)2(1,3-BDC)2]·0.25H2O的合成、结构和表征

The title complex, Mn₂(L)₂(1,3-BDC)₂]·0.25H₂O 1 (L=2-(2-chloro-6-fluorophenyl)-1H-imidazo4,5-f]1,10]phenanthroline and 1,3-H₂BDC=1,3-benzenedicarboxylic acid) has been obtained by using hydrothermal synthesis and characterized by elemental analysis, IR and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P2₁/n with a=1.751 68(6) nm, b=1.160 14(4) nm, c=2.585 30(8) nm, β=104.331(4)°, V=5.090 3(3) nm³, Z=4, C₅₄H_28.50Cl₂F₂Mn₂N₈O_8.25, M_r=1 140.13, D_c=1.488 g·cm^-3, F(000)=2 306, μ(Mo Kα)=0.673 mm^-1, R=0.060 5 and wR=0.161 6. The compound 1 exhibits two-dimensional wavy layer structures, which are further stacked through π-π interactions to form three-dimensional supramolecular architectures. CCDC: 760201.
