N2 - New π-d interacting system based on brominated TTF-type donor EDT-TTFBr2 (= 4,5dibromo-4′,5′- ethylenedithiotetrathiafulvalene) was investigated. Magnetic (EDT-TTFBr 2)2FeBr4 and non-magnetic (EDT-TTFBr 2)2GaBr4 are isostructural salts, which have strong anion-donor interaction through Br-Br atomic contacts with weak direct anion-anion interaction. The iron salt takes an antiferromagnetic transition at TN = 11 K owing to strong π-d interaction, which originates from the strong anion-donor interaction. The strong π-d interaction also plays an important role in the electron transport phenomenon in the variation of temperature and applied magnetic field.
