Tetrathiapentalene-based organic conductors with magnetic counter anions
An organic donor TTM-TTP (TTM-TTP (radical anion) 2,5-bis[4,5-bis (methylthio)-1,3-dithiol-2-ylidene]-1,3,4,6-tetrathiapentalene) forms 1:1 composition salts with metal halides. The salts of pure anions, (TTM-TTP)MX4(PhCl)(0.5) (M = Fe, Ga; X = Cl, Br) are dimerized insulators, whereas when the halogenes (Cl/Br) or the metals (Fe/Ga) are alloyed, metallic salts with uniform columns are obtained.
