A New Three-dimensional Supramolecular Polymer Built from Non-covalent Bonding Interactions
摘要:
A new complex, [Ni2(L)4(H2O)8](1, L1=4-(1H-imidazol-4-yl)benzoic acid), has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD. Complex 1 crystallizes in monoclinic, space group P21/c with a=22.281(2), b=7.3959(7), c=24.978(3) Å, β=90.876(10), V=4115.6(7) Å3, Z=8, C20H22N4O8Ni, Mr=505.13, Dc=1.630 g/cm3, μ=1.001 mm-1, S=1.080, F(000)=2096, the final R=0.452 and wR=0.1152 for 9380 observed reflections (I>2σ(I)). The result of X-ray diffraction analysis revealed three different kinds of Ni(Ⅱ) centre mononuclear molecules in the asymmetric unit. The independent mononuclear units are bridged to form a three-dimensional supramolecular polymer by extensive hydrogen bonds and C-H…π non-covalent bonding interactions.
