摘　　要：制备了超分子配合物[Mn(phen)2(NO3)]NO3.4H2O,利用元素分析仪、红外光谱仪、X射线单晶衍射仪分析了其组成和结构,并测定了其摩尔电导率.结果表明,合成的配合物晶体属三斜晶系,空间群P-1,晶胞参数分别为:a=0.791 38(19)nm,b=1.023 9(2)nm,c=1.647 3(4)nm,α=105.414(4)°,β=103.295(3)°,γ=90.127(4)°,V=1.249 4(5)nm3,Z=2.就配合物晶体结构而言,有机基团和结晶水通过氢键和π-π堆积作用扩展为二维超分子体系,其中结晶水通过氢键作用形成四核簇.A new supramolecular complex, EMn（phen）2 （NOa）]NO3·4H2 O, was synthesized. The composition and structure of as-synthesized complex were analyzed by elemental analysis and infrared spectrometry plus single crystal X-ray diffraction; and its molar conductance was measured as well. Results reveals that the complex belongs to triclinic system and space group P-l, with cell parameters beinga=0.79138（19）nm,b=1.0239（2）nm,c=1.6473（4）nm,α=105.414（4）°,β=103.295（3）°,）,=90.127（4）°,V=1.2494（5）nm3,Z=2 In terms of the crystal structure of the as-synthesized product, the organic moity and lattice water are packed by hydrogen bonding and 7r-n interactions to form a two-dimensional supramolecular network whose lattice water molecules are linked into tetranuclear water-clusters through the hydrogen-bond interaction.
