The new kappa-(BEDT-TTF)(2)SbF6 phase was grown by electrodeposition on a Si(0 0 1) electrode. This new phase was characterized by X-ray diffraction (XRD) and electronic conductivity measurements, accompanied by calculations of electronic band structures and Fermi surfaces. Below T = 120 K, a decrease in the electronic conductivity suggests a phase transition, attributed to anion ordering. (C) 2009 Elsevier B.V. All rights reserved.
