Thermal stability and specific heat of a new molecular complex of [60] fullerene with tetramethyltetraselenafulvalene (TMTSF), C-60.TMTSF.2(CS2), have been studied. The complex loses the solvent (CS2) stepwise in the temperature range of 80-190 degrees C. Decomposition of the complex with sublimation of TMTSF takes place at 220-370 degrees C. Analysis of the specific heat dependences C(T) has shown that the C-60 molecules are orientationally ordered in the complex, in contrast to the pristine C-60 A prominent maximum at T approximate to 6.5 K in the C(T)/T-3 dependence has been detected for the complex. it is proposed that nature of the maximum is related to the excitation of optical intramolecular vibrations of C-60 molecules.
Method of preparation of the fullerene-containing compound (ET(2)C(60))(2) . Fe(eta(5)C(5)H(5))(2) . xCS(2) is described. Basic physical properties, in particular FT IR transmission of the single crystals of the complex are studied and discussed. The complex is suggested to be used to grow large crystals of fulleride intercalated by Fe ions.
The structure of a new organic conductor, (BEDT-TTF)4Hg3I8, has been solved, temperature dependences on conductivity, thermopower and magnetic susceptibility studied. The BEDT-TTF molecules form two different types of stacks. At 260 K a jump in a conductor and thermopower takes place, characterized by a hysteresis of ca. 8 K. At this temperature the phase transition of the first order occurs in (BEDT-TTF)4Hg3I8. Below and above the transition temperature the conductivity has an activation character. At a pressure of 29 kbar the conductivity remains metallic up to 50 K. The paramagnetic susceptibility in this temperature range has a maximum.
AbstractThe title compound (I), which is a strong carbon acid, on reaction with the s‐trans‐enones (II) or with the nitroalkenes (IV) yields the 2‐amino‐1,5,5‐tricyano‐1‐cyclopentenes (III) or (V) with envelope conformation of the cyclopentene moiety.
AbstractSome adduct formations of the title compound (I) are investigated.
