2002
合成了苯并15-冠-5与Na2[M(SCN)4](M=Pd,Pt)生成的配合物:[Na(B15-C-5)]2[Pd(SCN)4](1),{[Na(B15-C-5)][Na(Bl5-C-5)(H2O)]}[Pt(SCN)4](2).1为单斜晶系,空间群P21/n,α=1.0164(6)nm,6=1.3743(3)nm,c=1.4987(7)nm,β=95.248(6)°,V=2.0847 nm3,Z=2,Dcalcd=1.47g/cm3,F(000)=944,R=0.053,wR=0.072.2为三斜晶系,空间群P1,α=1.1484(2)啪,b=1.4210(3)nm,c=1.5026(3)nm,α=62.500(3)°,β=72.393(3)°,γ=73.106(4)°,V=2.0398(7)nm3,Z=2,Dcalcd=1.674g/cm3,F(000)=1028,R1=0.0327,wR2=0.0885.1由两个[Na(B15-C-5)]+配阳离子和一个[Pd(SCN)4]2-配阴离子组成,两者通过Na-N键形成中性配合物,[Na(B15-C-5)]+相对钯原子呈反式排列.2由[Na(B15-C-5)]+和[Na(B15-C-5)(H2O)]+配阳离子和一个[Pt(SCN)4]2-配阴离子组成,它们也通过Na-N键形成中性配合物,配阳离子相对铂原子呈顺式排列.2的两个分子通过氢键形成二聚结构.
