合成了一维链状冠醚配合物:{[K(DB18-crown-6)]_2(CH_3CN)}[Pt(aSCN)_4],通过元素分析、红外光谱、单晶X-射线衍射对配合物结构进行表征,结果表明:配合物为单斜晶系,空间群c2/c a=2.590 4(8),b=1.365 4(4),c=1.817 0(6)nm,β=123.811(4)°,V=5.339(3)nm~3,Z=4,D_(calcd)=1.577g/cm~3,F(000)=2 552,R_1=0.051,wR_2=0.141 1.配合物由两个[K(DB18-crown-6)]~+配阳离子、一个[Pt(aSCN)_4]~(2-)配阴离子和一个CH_3CN分子组成,相邻[K(DB18-crown-6)]_2[Pt(aSCN)_4]离子对通过CH_3CN分子中的N原子形成一维链状结构。
A one-dimensional chain-like crown ether complex was synthesized by elemental analysis, infrared spectroscopy and single crystal X-ray diffraction (FTIR) The results show that the complex is monoclinic with c2 / ca = 2.590 4 (8), b = 1.365 4 (4), c = 1.817 0 ), V = 5.339 (3) nm ~ 3, Z = 4, D calcd = 1.577g / cm ~ 3, F000 = 2 552, R_1 = 0.051 and wR_2 = 0.141. A cluster of [K (DB18-crown-6)] ~ + cations, a [Pt (aSCN) 4] 2- anion and a CH 3 CN molecule adjoined [K The [Pt (aSCN) 4] ion pair forms a one-dimensional chain structure through the N atom in the CH 3 CN molecule.
