The coordination polymer, [Mn3（bpta）2（bip）2], （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 ...The coordination polymer, [Mn3（bpta）2（bip）2], （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/c with a = 14.919（3）, b = 9.780（2）, c = 20.352（7） A, V = 2344.4（10） A3, Z= 2, C52H32Mn3N10012, Mr = 1153.70, Dc = 1.634 g/cm3, p（MoKa） = 0.876 mm-1, F（000） = 1170, the finalR = 0.0605 and wR = 0.1177. The complex forms a 2D layer with trinuclear Mn（II） units and further assembles into a 3D supramolecular network structure through C-H..＇O hydrogen bonding and C-H...π interactions. Moreover, the negative J value indicates the presence of antiferromagnetic coupling between the Mn（II） ions within a trinuclear unit.展开更多

The backbones of the two types of adip dianions link the neighboring trinuclear Mn（Ⅱ） clusters to yield a two-dimensional layer structure. The large conjugated L ligands are located on both sides of the two-dimensional layers. Additionally,the O-H···O,O-H···N and N-H···O hydrogen bonds further stabilize the structure.展开更多
