Abstract
X-Ray structural and EPR spectroscopic studies of the redox-related pairs [ WX(CO)(MeC=CMe)Tp'](z) (X = F, Cl, Br and I; z = 0 and 1) [Tp' = hydrotris( 3,5-dimethylpyrazolyl)borate] are consistent with the HOMO of the d(4) (z = 0) species being pi-bonding with respect to the W-CO bond, pi-antibonding with respect to the W-X bond, and delta-bonding with respect to the W-alkyn e bond.
