Abstract: In the title centrosymmetric complex, trans-[PtCl₂(C₆H₁₀N₂)₂], the Pt^II centre is coordinated by two piperidine-1-carbonitrile ligands and two chloro ligands, resulting in a typical square-planar geometry. The C-N distance between the nitrile and piperidine group [1.306 (4) Å] clearly indicates that this bond is not a pure single bond, being closer to a C=N double bond. This points to a noticeable contribution of the bipolar structure [Pt]-N^-=C=N⁺R₂ in the resonance hybrid of the push-pull nitrile ligand.
