摘　　要：研究了 18 冠 6( 18 C 6)与KSCN ,CdCl2 ·2 5H2 O ,(Bu4N) 2 [Zn(dmit) 2 ] (dmit =4,5 dimercapto 1,3 dithiole 2 thione ,C3 S52 -)的反应 ,生成的标题配合物 ( 1)通过元素分析、红外光谱、单晶X射线衍射进行了表征 .配合物属单斜晶系 ,空间群C2 /c.晶体学数据 :a =3 4780 ( 7)nm ,b =1 5 170 ( 3 )nm ,c =2 844 0 ( 6)nm ,β =10 5 93 ( 3 )° ,V =14 42 7( 3 )nm3 ,Z =8,F( 0 0 0 ) =7872 ,R1=0 0 42 5 ,wR2 =0 0 73 9.配合物由一个Bu4N+ 阳离子和一个 {[K( 18 C 6) ] [Cd4(dmit) 2 (dmt) 3 ] }-(dmt =4,5 dimercapto 1,2 dithiole 3 thione ,C3 S52 -)配阴离子组成 .{[K( 18 C 6) ] [Cd4(dmit) 2 (dmt) 3 ] }-通过K…S ,S…A novel 18-crown-6 (18-C-6) complex, (Bu4N){[K(18-C-6)][Cd-4(dmit)(2)(dmt)(3)]} (dmit = 4,5- dimercapto-1,3-dithiole-2-thione, dmt = 4,5-dimereapto-1,2-dithiole-3-thione, C3S52-) (1), has been synthesized and characterized by elemental analysis, IR spectrum and, X-ray diffraction analysis. The complex belongs to monoclinic, space group C2/c with cell dimensions, a = 3.4780(7) nm, b = 1.5170(3) nm, c = 2.8440(6) nm, beta = 105.93(3)degrees, V = 14.427(3) nm(3), Z = 8, F(000) = 7872, R-1 = 0.0425, wR(2) = 0.0739. The complex is composed of one Bu4N+ cation and one {[K(18-C-6)][Cd-4(dmit)(2)(dmt)(3)]}(-) complex anion. In the crystal, {[K(18-C-6)][Cd-4(dmit)(2)(dmt)(3)]}(-) complex anions show a three-dimensional network structure bridged by (KS)-S-... and (SS)-S-... weak interactions.
