Organic-inorganic layer compounds as molecular functional materials
Many molecular charge transfer salts synthesised over the last 20 years contain alternating layers of organic donor cations and inorganic metal-complex anions. Here we survey some features of one of the most prolific families of such salts: (BEDT-TTF)(4)[AM(C(2)O(4))(3)]. G, where BEDT-TTF is bis-ethylene-dithiotetrathia-fulvalene, A is a monopositive cation, M a tri-positive cation and G an organic guest molecule. The roles of anion chirality, molecular conformational disorder and the formation of superlattice ordering of layer packing are emphasised.
