Title: [{Fe(tim)}2]: an Fe-Fe dimer containing an unsupported metal-metal bond and redox-active N4 macrocyclic ligands. Author: Hess CR, Weyhermüller T, Bill E, Wieghardt K. Journal: Angew Chem Int Ed Engl; 2009; 48(20):3703-6. PubMed ID: 19378307. Abstract: 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.[Abstract] [Full Text] [Related] [New Search]
