Abstract：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.
