摘要：

No support required: Unlike the unobservable radical cations [{CpM(CO) 3}2].+ (M=W, Mo), derivatives [{CpM(CO) 2(PMe3)}2].+ are stable enough to be isolated and characterized. Experimental and theoretical studies show that the shortened M-M bonds are of order 1 1/2, and that they are not supported by bridging ligands. The unpaired electron is delocalized over the M-M cores, with a spin density of about 45 % on each metal atom. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
