A tri-σ-aryl vanadium(III) derivative: structural determination of trimesitylvanadium(III)–tetrahydrofuran
Abstract
The reaction of [VCl3(thf)3] with MesMgBr (Mes = 2,4,6-Me3C6H2; thf = tetrahydrofuran) in thf led to the isolation of [VMes3(thf)] as blue crystals; an X-ray crystal structure determination showed that it contained monomeric pseudotetrahedral vanadium(III)(µeff. 2.73 µB at 298 K) binding a thf molecule and three mesityl ligands, with the V–C bond distances ranging from 2.099(6) to 2.116(7)Å.
