摘　　要：采用N-烯丙基咔唑配体与三氨三羰基合铬在二氧六环中回流反应,合成了标题化合物。通过元素分析I、R、1HNMR1、3CNMR、MS和X射线单晶衍射对其结构进行了表征。晶体结构分析表明,该化合物属于三斜晶系,空间群P-1,a=8.136 2(11),b=10.254 6(14),c=10.887 3(15),α=99.671(3)°,β=108.810(2)°,γ=111.073(2)°,Z=2。比较了目标化合物与其自由配体的电子吸收光谱,并用飞秒Z-扫描技术研究了目标配合物的非线性光学性质。N-allylcarbazole chromium tricarbonyl （ AKC, C18 H13-CrNO3 ） was synthesized as a racemic mixture of two enantiomers by treating the free ligand with（NH3）3Cr（CO）3 during refluxing and was characterized by elemental analysis, IR, ^1HNMR, ^13CNMR and MS.The crystal structure of AKC was determined by the single-crystal X-ray diffraction analysis. The crystal was a triclinic system of a space group P-1,with a = 8.136 2（ 11）A, b = 10.254 6（14）A, c = 10.887 3 （15）A, α = 99.671 （3）°, β = 108.810（2）°, γ = 111.073（2）°, and Z = 2.The nonlinear optical absorption of N-allylcarbazole chromium tricarbonyl solution （in DMF） was measured by femtosecond Z-scan technique at a wavelength of 800 nm.
