STRUCTURES AND PROPERTIES OF NEW CHARGE-TRANSFER COMPOUNDS DERIVED FROM ORGANIC DONOR MOLECULES AND INORGANIC POLYOXOANIONS PM12O40(3-) AND M6O19(2-), WHERE M = MO, W

A series of new charge-transfer salts based on TTF, BEDT-TTF and several polyoxometalate ions have been synthesized and characterized. In the case of TTF derivatives two types of compounds have been isolated. The first show a distorted one-dimensional structure, while the second contain completely ionized and dimerized (TTF+.)2. A relationship between the crystal structure and the physical properties in these materials is discussed. Electrolysis of BEDT-TTF at constant current in the presence of (But4N)2 Mo6O19 gave a black microcrystalline product of formula (BEDT-TTF)2 Mo6O19.
