摘要The coordination polymer, [Mn3(bpta)2(bip)2]n (H3bpta = biphenyl-3,3',5-tricar- boxylic acid, bip = 2,6-bis(imidazole-1-yl)pyridine), has been synthesized under hydrothermal con- ditions and characterized by elemental analysis, FT-IR, XRD, TGA and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/cwith α = 14.919(3), b = 9.780(2), c = 20.352(7) Å, V = 2344.4(10) Å3, Z = 2, C52H32Mn3N10O12, Mr = 1153.70, Dc= 1.634 g/cm3, μ(MoKα) = 0.876 mm-1, F(000) = 1170, the final R = 0.0605 and wR = 0.1177. The complex forms a 2D layer with trinuclear Mn(II) units andfurther assembles into a 3D supramolecular network structure through C–H···O hydrogen bonding and C–H···π interactions.
