摘    要:A novel manganese coordination polymer [Mn2(sfdb)2(biyb)2(H2O)2]n (1, H2sfdb=4,4′-sulfonyldibenzoic acid, biyb=1,4-bis(imidazol-1-ylmethyl)benze) has been hydrothermally synthesized and structurally characterized by single-crystal X-ray determination, IR and thermogravimetric analysis (TGA). Complex 1 crystallizes in the triclinic system, space group P with a=10.138(4), b=11.187(5), c=13.582(6) γ, α=69.146(7), β=89.628(7), γ=77.076(7)°, Mn2C56H48N8O14S2, Mr=1231.02, V=1398.5(10) ·3, Dc=1.462 g/cm3, F(000)=634, μ=0.600 mm-1, S=1.088 and Z =1. The final refinement gave R=0.0570 and wR=0.1229 for 4889 observed reflections with I > 2σ(I). Interestingly, in complex 1, the sfdb2- and biyb ligands connect the Mn(II) ions into two-dimensional 2-fold interpenetrating layers, and such layers are further connected with each other to generate a 3D supramolecular structure through hydrogen bonding interaction.
