Comment on “Hydride, gold(i) and related derivatives of the unsaturated ditungsten anion [W2Cp2(μ-PCy2)(μ-CO)2]−” by M. A. Ruiz et al., Dalton Trans., 2014, 43, 16044
Abstract
Application of the covalent bond classification to the compounds [M2(η5-C5H5)2(μ-H)(μ-PCy2)(CO)2] (M = Mo, W) identifies the compounds as having two M–M bonds and a 2 electron 3 centre (2e–3c) bond incorporating the bridging hydrogen, in accord with density functional calculations, and assigns their class as ML4X4.
