摘要

合成了新颖苯并18冠6配合物{Na(B18-C-6)]6[Pt(SCN)6]}[Pt(SCN)6](SCN)2,通过红外光谱、单晶X-射线衍射对该配合物进行了表征.配合物为三方晶系,空间群为R-3,晶体学数据a=b=1.993 3(3),c=2.976 0(6)nm,a=β=90,γ=120°,V=10.240(3)nm3,Z=3,Dcalcd=1.564 g/cm3,F(000)=4 908.配合物由一个配阴离子[Pt(SCN)6]2-与一个配阳离子{[Na(B18-C-6)]6[Pt(SCN)6]}4+和两个SCN-阴离子组成.相邻{[Na(B18-C-6)]6[Pt(SCN)6]}4+通过Na-O键相互作用形成三维网状结构.[Pt(SCN)6]2-配阴离子和两个SCN-阴离子起平衡电荷的作用.%The novel benzo-18-crown-6 (B18-C-6) complex: {[Na(B18-C-6)]6[Pt(SCN)6]}[Pt (SCN)6](SCN)2(1)was synthesized and characterized by elemental analysis,IR spectrum and xray diffraction analysis. Thr crystal structure belongs to rhomobohedral, space group R-3 with cell dimesions :a=b=1.993 3(3),c=2. 976 0(6) nm,α=β=90,r=120°,V=10. 240(3) nm3,Z=3,Dcalcd=1. 564 g/cm3,F(000)=4 908.1 is composed of one {[Na(B18-C-6)]6[Pt(SCN)6]}4+complex cation,one [Pt (SCN)6]2- complex anion and two SCN anions. {[Na (B18-C-6)]6 [Pt (SCN)6]}4+ complex cation shows a three-dimensional network structure bridged by Na-O interactions between adjacent [Na (B18-C-6)]+ units. The function of [Pt (SCN)6]2- complex anion and two SCN- anions are balancing charge in crystal.
