New two-dimensional organic metals ET2[Hg(SCN)3-nXn], X=F,C1,Br,I have
been synthesized and investigated. ET2[Hg(SCN)Cl2](I) and ET2[Hg(SCN)
2Cl](II) are isostructural. Cationic sheets of kappa-type alternate wi
th anionic sheets. The anions [Hg(SCN)3-nCln]-(n=1,2) have a polymeric
structure and form the chains with one or two bridge ligand SCN. Both
salts have a metallic character of conductivity till 35 K (I) and 50
K (II), respectively, at lower temperatures they become insulators.
