摘要：

New two-dimensional organic metals ET2[Hg(SCN)3-nXn], X=F,Cl,Br,I have been synthesized and investigated. ET2[Hg(SCN)Cl2] and ET2[Hg(SCN)2X] (X=Cl,Br or (0,33 Cl+0,66 Br) have been found isostructural. Cationic sheets of kappa-type alternate with anionic sheets. The [Hg(SCN)3-nXn] (n=1,2) anions have a polymeric - structure and form chains with one or two SCN bridge ligands. The conductivity of salts with X=F is of a metallic character down to helium temperature, while all salts with X=Cl(n=1,2), (Cl 0,33 Bro,66), Br exhibit metallic behaviour of their conductivity till 35, 50, 70 and 140 K, respectively, then they become insulators The salt with X=I is semiconductor.
