Abstract
We report the preparation, structural and physical investigations of B EDT-TTF (ET) salts formulated beta-ET5M(CN)(6), 10 H2O with M = Fe-III and Co-III and kappa-[Et4N] (ET)(4)M(CN)(6), 3 H2O with M = Fe-III, C o-III and Cr-III, The kappa-phase salts show two phase transitions at 240 K and 150 K, respectively. The first structural transition, at 240 K, is followed by a redistribution of the charges on the ET molecules and the magnetic and electrical properties are explained on the basis of this phenomenon, A facile and convenient route for the preparation of the (R4N)(3)M(CN)(6) [R = C2H5 and C4H9) salts is also presented.
