Abstract
We report the preparation, structural and physical investigations of B EDT-TTF (ET) salts formulated kappa-[Et4N](ET)(4)M(CN)(6), 3 H2O (M = Fe-III, Co-III, Cr-III). These kappa-phases show two phase transitions at 240 K and 150 K. The first structural transition, at 240 K, is fol lowed by a redistribution of the charges on the ET molecules and the m agnetic and electrical properties are explained on the basis of this p henomenon.
