The η4‐dienes are displaced by monodentate CO or isocyanide ligands to provide derivatives where both W≡C bonds coordinate to a single Pt0 center, attended by significant distortion of the WCCW spine.We are grateful to the Australian Research Council (DP170102695 and DP190100723) for funding.5 pagesapplication/pdfen-AU© 2019 Wiley-VCH Verlag GmbH & Co.
