The synthesis of a square planar cationic Pd(II) complex containing the acetamide ligand is described. The complex has been characterised by X-ray diffraction, leading to one of the rare examples of a crystal structure showing an acetamide molecule coordinated to a metal centre and, to the best of our knowledge, the first one with palladium. This complex may be relevant to catalytic reactions, such as the palladium-catalysed amidocarbonylation, in which transient species with O-coordinated acetamide can be formed.

Nous décrivons la synthèse d'un complexe cationique du palladium (II) avec le ligand acétamide. Ce complexe a été caractérisé par diffraction des rayons X, conduisant à l'une des rares structures cristallographiques montrant la coordination de NH 2 C(O)Me à un centre métallique par l'atome d'oxygène et, à notre connaissance, la première dans le cas de complexes du palladium. Il est probable que des complexes similaires se forment de manière transitoire dans des processus catalytiques impliquant l'acétamide, comme par exemple les réactions d'amidocarbonylation catalysées par des complexes du palladium.
