New organic metals based on et and d/sub 8/-ET with polymeric metal containing anions

Summary form only given. 1. A number of organic metals with deuterated ET (d/sub 8/-ET) has been synthesized and comparative analysis of the structure and properties of these salts with analogous ET-based salts are proposed. It is found that a) the salt (d/sub 8/-ET) /sub 4/ (Hg/sub 2/Br/sub 6/HgBr/sub 2/) transits to superconducting state with T/sup c/=4 K at p=0.3kbar, b) the salt (d/sub 8/-ET)/sub 2/[Hg(SCN)/sub 2/Br] has k-type structure of the cation layer and metal-insulator transition below 100 K, c) the salt (d/sub 8/-ET)/sub 4/[Hg(SCN)/sub 2/C1]/sub 2/ compared with protonated analogous has different structure as anion so cation layers and metal-insulator transition below 120 K, d) the salt (d/sub 8/-ET)/sub 4/Hg/sub 3/I /sub 8/ has first order semiconductor-semiconductor transition at T/sub c/=265 K. 2. The construction of polymeric anions, structure and properties of new ET-based salts with polymeric anions (CuHg(SCN)/sub 4//sub 2/ and (Pb/sub 3/Br/sub 9/) are discussed.
