摘　　要：以烟酸(4-烯丙基-2-甲氧基)苯酯(L)为配体,在四氢呋喃/水体系中设计合成了银-双键配位的新型配合物[AgL(NO_3)]_n(1)。通过X-射线单晶衍射方法对L和1进行了表征,分析了其光谱及结构特征。结构分析表明,化合物L和1都为单斜晶系,配体L通过C-H…O氢弱作用依次形成二聚体、二维层结构。配合物1中,含有通过银-双键和氮原子配位的左旋曲绕链和通过银-氧弱作用形成的右旋曲绕链,两种链通过…ABAB…堆积形成二维结构,最后通过C-H…O弱作用形成三维结构。同时对化合物L和1的荧光性质进行了研究。One new alkene complexe of silver 髣, [Ag L（NO3）]n（1）,（L=4-allyl-2-methoxyphenyl nicotinate） has been prepared by self-assembly of Ag NO3 with 4-allyl-2-methoxyphenyl nicotinate（L） in THF/H2 O system. The structures of compounds L and 1 are determined by X-ray diffraction analysis. The crystals of the two compounds belong to the monoclinic space group. Compound L is connected to form a dimer, 2D layer sequentially by the weak C-H…O hydrogen bonds. The structure of 1 consists of 1D left-handed helical chains of [Ag L]∞in which the allyl arms and N atoms are coordinated to silver atoms, and right-handed helical chains of [Ag NO3]∞connecting through the Ag-O weak interactions. Two kinds of helices are connected in …ABAB… fashion to form a 2D achiral layer. Finally, the resulted 2D net extents to the 3D supramolecular architecture by the weak C-H…O interactions. In addition, the photoluminescence of L and 1 has been investigated in detail. CCDC： 985940,L; 985941, 1.
