摘　　要：通过六水合硝酸镍,D-樟脑酸和三乙醇胺在甲醇溶剂中反应得到一种新型的手性镍樟脑酸配合物即[Ni(teaH_(3))](D-cam).X-射线单晶衍射结果表明该晶体属正交晶系,结晶于P2_(1)2_(1)2_(1)空间群,为一维右手单螺旋链状结构,其螺旋周期为7.62Å.化合物的最小不对称单元包含一个单核金属Ni离子、一个未脱质子的三乙醇胺分子和一个D-樟脑酸根离子.化合物1的分子简式为C_(16)H_(29)NO_(7)Ni.同时,还对该化合物进行了热重分析和X-射线粉末衍射表征.最后圆二色谱(CD谱)进一步表明其纯手性特征.The reaction of D-camphoric acid and triethanolamine with Ni(NO_(3))_(2)·6H_(2)O in methanol solvent provided a novel chiral coordination polymer based on camphorate-Ni,namely[Ni(teaH_(3))](D—cam).The X-ray single crystal diffraction analysis indicates that compound 1 crystallizes in the orthorhombic space group P2_(1)2_(1)2_(1),and shows an one-dimensional right-handed homohelical structure with a helix period of 7.62Å.The asymmetric unit of compound 1 consists of mononuclear Ni ion,one neutral triethanolamine molecule,and one D-camphorate ligand.The molecular formula of compound 1 is C_(16)H_(29)NO_(7)Ni.Meanwhile,compound 1 was characterized by thermogravimetric analysis and X-ray powder diffraction.Finally,the circular dichroism(CD spectrum)further confirmed its homochiral characteristics.
