Crystal structures and physical properties have been investigated for two cation radical salts formed with EOET, which is a hybrid molecule between ET and BO. The Mott-insulating -(EOET) 2Cu[ N(CN) 2] Br salt has a spin-singlet ground state, while the -(EOET) 2GaCl 4 salt with a triangular lattice composed of EOET dimers shows a metal-insulator transition at around 40 K. Key words. EOET - , crystal - structure, electron paramagnetic resonance, - metal-insulator transition.
