The review provides a survey of the key classes of Pt II complexes containing cis ‐{Pt(η 1 ‐hydrocarbyl)(η 2 ‐unsaturated ligand)} moieties, which have been isolated or at least unequivocally characterized in solution. These compounds, which mimic reactive intermediates of fundamental catalytic processes, have been classified in four general types, which display a cis arrangement of an alkyl group and a monoalkene ( I ), an aryl group and a monoalkene ( II ), an alkyl group and a monoalkyne ( III ), and an aryl group and a monoalkyne ( IV ). A discussion of their main structural and chemicalfeatures, disclosing the factors affecting their reactivity, dynamic behavior, and relative stability, is presented. In some remarkable cases ( III and IV ), it is the cis arrangement of the hydrocarbyl fragments that promotes unusual reactivity.
