Abstract

Three charge transfer salts derived from the MET (4,5-methylenedithio-4′,5′-ethylenedithiotetrathiafulvalene) donor molecule have been synthesized: (MET)ClO4and isostructural (MET)PF6crystallize in the monoclinic space group C 2/m, Z = 2, with unit cell dimensions a = 13.842(3) A ̊, b = 10.255(3) A ̊, c = 5.842(1) A ̊, β = 104.31(2)°, Vc= 803.6(3) A ̊3and a = 14.146(4) A ̊, b = 10.521(2) A ̊, c = 5.901(1) A ̊, β = 105.02(2)°, Vc= 848.2(3) A ̊3, respectively, and (MET)3(ReO4)2is triclinic, P1, Z = 1, with unit cell dimensions a = 8.007(6) A ̊, b = 9.814(6) A ̊, c = 15.526(9) A ̊, α = 90.90(5)°, β = 90.85(6)°, γ = 110.58(5)°, Vc= 1142(2) A ̊3. Single crystal electrical conductivity and ESR measurements show that these salts all exhibit semiconducting behavior. A structural phase transition is observed in the 1:1 (MET)ClO4salt at ≅ 180 K and is indicated in the 1:1 (MET)PF6salt on the basis of low temperature ESR data. The packing of the donor molecules in the two 1:1 salts is similar to that previously reported in (BEDSe-TSeF)PF6. The structure type observed for (MET)3(PF6)2is most closely related that observed in 3:1 MT salts. © 1988.
