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.
The composition and structure of supramolecular complex [Mn (phen) 2 (NO3)] NO3.4H2O were investigated by elemental analysis, infrared spectroscopy and X-ray single crystal diffraction and their molar conductivities were determined. The results show that the crystal of the synthesized complex belongs to the triclinic system with space group P-1 and the unit cell parameters are as follows: a = 0.791 38 (19) nm, b = 1.023 9 nm, α = 105.414 (4) °, β = 103.295 (3) °, γ = 90.127 (4) °, V = 1.249 4 (5) nm3 and Z = 2. For the crystal structure of the complex, The crystal water expands into a two-dimensional supramolecular system through hydrogen bonding and π-π stacking, in which crystal water forms tetranuclear clusters through hydrogen bonding.
