合成了新型三元有机导体(BEDT-TTf)2 mm‘(SCN)4[M=K，Rb，Cs；M’=Co，Zn，Cd]。对α-Et2CsCo(SCN)4、EtZn(Scn)3、α-Et2RbZn(Scn)4、α-Et2CsZn(Scn)4、α-EtCd0.66(Scn)2和Et2CsCd(Scn)4进行了晶体结构分析。大多数盐具有α类型的施主排列和厚阴离子层中类似[···M‘2+···(SCN)−···M+···]的聚合物片层。尤其是α-(BEDT-TTf)2CsM‘(SCN)4[M’=Co和Zn]是低至20K的金属。
New three-component organic conductors, (BEDT-TTF)2MM′(SCN)4 [M = K, Rb, Cs; M′ = Co, Zn, Cd], are prepared. The crystal structure analyses of α-ET2CsCo(SCN)4, ETZn(SCN)3, α-ET2RbZn(SCN)4, α-ET2CsZn(SCN)4, α-ETCd0.66(SCN)2, and ET2CsCd(SCN)4 are carried out. Most of salts have the α-type donor arrangement and the polymer sheet like [···M′2+···(SCN)−···M+···] in a thick anion layer. Especially α-(BEDT-TTF)2CsM′(SCN)4 [M′ = Co and Zn] are metallic down to 20 K.
