Re(I) complexes, studied in acetonitrile, the transitions associated with the lowest-energy absorption band are of 1MLCT (metal-to-ligand charge transfer) nature. The emission properties, as observed at room temperature and at 77 K, can be described as follows: (i) the Fe(II) complexes do not emit, either at room temperature or at 77 K; (ii) the room-temperature emission of the Ru(II) complexes (φem
