摘　　要：将配体反式-双(苯甲酰丙酮)-1,4-环己二胺(L)与Ag X(X=NO3-,BF4-,Sb F6-,Cl O4-)进行反应得到4个配合物{[Ag(L)]NO3}n(1),{[Ag(L)(H2O)]BF4}n(2),{[Ag2(L)3](Sb F6)2}n(3),{[Ag(L)]Cl O4}n(4),并用元素分析,红外和X-射线单晶衍射表征了4个配合物的结构。在固体状态下,配合物1和2都形成2D网状结构的配位聚合物,都有2个不同配位类型的配体,不同的是,配合物1中桥连配体的1,4-环己二胺1,4位的C-N键在直立键上,而配合物2中桥连配体的1,4-环己二胺中1,4位的C-N键在平伏键上;配合物3也有2种不同配位类型的配体,但是与配合物1和2不同,配合物3形成1D配位聚合物;配合物4中的配体只有一种配位类型,配合物4形成2D网状结构。4个配合物中,配合物2,3的阴离子未参与Ag(Ⅰ)配位,配合物1和4的阴离子与Ag(Ⅰ)配位。同时,研究了配体和配合物在室温下的固态荧光性质。Four complexes, {[Ag（L）]NO3}n （1）, {[Ag（L）（H2O）]BF4}n （2）, {[Ag2（L）3]（SbF6）n}, （3）, {[Ag（L）]ClO4}, （4）, were synthesized by treating chelating ligand trans-bis（benzoylacetone）-l,4-diaminocyclohexane （L） with AgX （X=NO3-, BF4-, SbF6-, ClOg-）. The structures of these complexes were characterized by elemental analysis, infrared spectroscopy, and X-ray single-crystal diffraction. In the solid state, the ligands in the 2D networks of 1 and 2 exhibited two types of coordination modes： in 1, the CN bonds of the bridging ligand, 1,4-diaminocyclohexane, were axial, while in 2, the CN bonds were equatorial. On the other hand, the ligands in 3 exhibited two types of coordination modes, which formed only 1D complexes. coordination mode, which formed a 2D network. Anions in Moreover, the ligands in 4 exhibited only one type of 2,3 were not coordinated to Ag（I）; However, 1 and 4 were coordinated to Ag （I）. Meanwhile, the solid-state fluorescence of ligands and complexes was studied at room temperature.
