A new crystallographic modification ({Kappa}{sub L}{sup `}) was found in the BEDT-TTF:M(CF{sub 3}){sub 4}{sup -}: solvent (M=Cu, Ag, Au) system. The structure of monoclinic {Kappa}{sub L}{sup `}-(BEDT- TTF){sub 2}Cu(CF{sub 3}){sub 4}(1,2-dibromo-1-chloroethane = DCBE) is reported. It differs from the orthorhombic {Kappa}{sub L}{sup `}- phase by having all BEDT-TTF molecules tilted in the same direction with respect to the conducting phase normal, whereas in {Kappa}{sub L} the tilt direction alternates between layers.
