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

It crystallizes in triclinic,space group P1^- with a = 8.4085(11) ,b = 11.1273(14) ,c = 14.5758(18) ,α = 78.528(2) ,β = 75.425(2) ,γ = 78.143(2) °,V = 1276.0(3) A^3,Z = 1,C56H50F2Mn3N8O14,Mr = 1261.86,Dc = 1.642 g/cm^3,F(000) = 647,μ(MoKa) = 0.819 mm^-1,R = 0.0446 and wR = 0.1008. 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
