摘要
二环己基18-冠-6(DC18C6,异构体A和B的混合物)与Na2[Pd(i-mnt)2][i-mnt=异丁二腈烯二硫醇阴离子,C2S2(CN)22-]反应,得到了配合物[Na(DC18C6-A)]2[Pd(i-mnt)2](1).通过元素分析、核磁共振氢谱和红外光谱对配合物进行了表征.X-射线单晶衍射测定了配合物的晶体结构.配合物为三斜晶系,空间群P1.1的晶体学数据:a=1.017 5(6)nm,b=1.195 8(7)nm,c=1.259 5(7)nm,α=102.790(10)°,β=109.117(9)°,γ=99.024(10)°,V=1.367 6(13)nm3,Z=1,Dc=1.430 g/cm3,F(000)=616,R1=0.057 4,wR2=0.120 4.在1中,Na+离子选择了DC18C6-A并与其六个O原子成键形成配阳离子[Na(DC18C6-A)]+,每个配阳离子皆与相邻的两个配阴离子[Pd(i-mnt)2]2-以N-Na-N作用将1构筑成一维链状结构.
The novel complex[Na(DC18C6-A)]2[Pd(i-mnt)2](1) was synthesized by the reactions of dicyclohexyl- 18-crown- 6 (DC18C 6) with Na 2 [Pd (i-mnt) 2 ] [i-mnt = 1,1-dicyanoethene- 2,2-dithiolate, C2S2 (CN)2^2-]and characterized by elementary analysis,1^H NMR and IR spectroscopy. The crystal structure was determined by X-ray single crystal diffraction. The complex 1 crystallize triclinic, space group Plwith crystallographic data:a=1. 017 5(6) nm, b=1. 195 8(7)nm,c=1. 259 5(7)nm,α=102. 790 (10)°,β=109. 117(9)°,γ=99. 024(10)°,V=1. 367 6(13)nm^3,Z=1,Dc=1. 430 g/cm^3,F(000)= 616,R1 = 0. 057 4,wR2 = 0. 120 4. In complex 1,Na^+ cation was distinguished by DC18C6-A and they formed the complex cation [Na (DC18C6-A)]^+. The complex displays an one-dimensional chain of complex cations [Na (DC18-C-6-A) ]^+ and complex anion[Pd (i-mnt)2]^2- bridged by N-Na-N interacuions.
