The 2:1 charge-transfer (CT) salts of a new donor molecule, ethylene-diselenotetrathiafulvalenothioquinone-1,3-dithiolemethide with a magnetic FeBr 4- ion and a nonmagnetic GaBr 4- ion were prepared, whose crystal structures and electrical con-ducting/magnetic properties were investigated. Key words. New donor molecule - magnetic and nonmagnetic counteranions - charge-transfer salt - crystal structure - electrical conducting and magnetic properties - $\pi $-d interaction.
