摘　　要：在水热条件下用氯化锰和咪唑基配体合成了配合物Mn[(IPB)_2Cl_2]·4H_2O(IPB=4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)benzaldehyde),并通过元素分析、红外光谱、紫外衍射、X射线单晶衍射法和Z-扫描技术对其结构和性质进行了表征。X射线单晶衍射结果表明,该化合物晶体属正交晶系,空间群Pnna。采用Z-扫描技术测量了该化合物的非线性光学特性,结果显示,以45μJ的脉冲能量,在焦点处的透光率为93%,非线性吸收系数为-4.5×10-11 m·W-1,非线性折射率为1.0×10^(-19) m^2·W^(-1)。该化合物显示了自聚焦的性质。在紫外-可见光谱区,该化合物的最大吸收波长为282nm。The complex Mn[（IPB）2Cl2]·4H2O （IPB=4-（1H-imidazo[4,5-f] [1,10]phenanthrolin-2-yl） benzaldehyde） was synthesized and characterized by elemental analysis, IR, UV-Vis, X-ray diffraction and the Z-scan technique. The X-ray diffraction results revealed that the complex crystallizes in Pnna space group of orthorhombic crystal system. The nonlinear optical properties were measured by the Z-scan technique and yielded a normalized transmittance of about 93% for the complex with a 45 μJ pulse at the focal point, and the nonlinear absorption coefficient, β, is -4.5×10-11 m·W-1, the nonlinear refractive index, γ, is 1.0×10-19 m2·W-1. The complex shows a self-focusing property. In the range of the UV-Vis spectrum, the maximum absorption wavelength is at 282 nm for the complex.
