Scanning electron microscope (SEM) and energy dispersive X-ray analyses (EDX) of the structures of the (BEDT-TTF) x /(AuI) and (BEDT-TTF) x /(AuI 3 ) composites have been performed. It was shown that the light spots in the SEM images are mainly given by microparticles of free Au. On the other hand, the grey areas in the images should be attributed mainly to (BEDT-TTF) 2 I 3 and (BEDT-TTF) 2 AuI 2 grains. It was shown also, that the composite annealing leads to subsequent completion of the charge-transfer (CT) reaction.
