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。
The ligand trans-bis (benzoylacetone) -1,4-cyclohexanediamine (L) was reacted with Ag X (X = NO3-, BF4-, Sb F6-, Cl O4-) The complexes {[Ag (L)] NO3} n (1), {[Ag (L) (H2O)] BF4} n (2), {[Ag2 (L) 3] (Sb F6) 2} n ), {[Ag (L)] Cl O4} n (4). The structures of four complexes were characterized by elemental analysis, IR and X-ray single crystal diffraction. In the solid state, both complexes 1 and 2 form a 2D network of coordination polymers, each of which has 2 ligands of different coordination type, with the exception that 1,4 - cyclohexanediamine 1,4 position of the CN bond on the upright bond, and ligand 2 in 1,4-cyclohexanediamine bridge ligand 1,4 1,4-bond on the phenolic bond; complex 3 also has two ligands of different coordination types, but unlike complexes 1 and 2, complex 3 forms a 1D coordination polymer; the ligand in complex 4 has only one coordination type and complex 4 forms a 2D grid. Among the four complexes, the anions of complexes 2 and 3 did not participate in the coordination of Ag (Ⅰ). The anions of complexes 1 and 4 coordinated with Ag (Ⅰ). Meanwhile, the solid-state fluorescence properties of ligands and complexes at room temperature were studied.
