beta''-(BEDT-TTF)(4)](H3O)Cr(C2O4)(3)]CH2Cl2: Effect of included solvent on the structure and properties of a conducting molecular charge-transfer salt
The new charge-transfer salt beta "-(BEDT-TTF)(4)[(H3O)Cr(C2O4)(3)]S, where BEDT-TTF = bis(ethylenedithio)tetrathiaful valene and S = CH2Cl2, has a broad metal-insulator transition at approximately 150 K. This differs from similar salts in the BEDT-TTF tris(oxalato) metalate Series, notably the superconducting materials with S = PhCN and the salt with S = C5H5N, which has a sharp metal-insulator transition.
