将配体反式一双(苯甲酰丙酮)-1,4-环己二胺(L)与AgX(X=NO3-,BF4-,SbF6-,ClO4-)进行反应得到4个配合物{[Ag(L)1N03}n(1),{[Ag(L)(H2O)IBF4}n(2),{[Ag2(L)3](SbF6)2}n),{[Ag(L)ICIO4}n(4),并用元素分析,红外和X一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Ad(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.
