摘要：
Mixed doubles: The dimeric complex [{Fe(tim)}2] (see structure, tim=2,3,9,10-tetramethyl-1,4,8,11-tetraazacyclotetradeca-1,3,8,10-tetraene) represents an unprecedented complex containing an unsupported Fe - Fe bond. The crystal structure confirms the presence of reduced tim units, thus indicating ligand redox activity. Spectroscopic and computational studies establish a triplet ground state for [{Fe(tim)}2] and suggest a mixed-valence compound with respect to both the Fe ions and the ligands. © 2009 Wiley-VCH Verlag GmbH & Co.
