Abstract
In the title centrosymmetric complex, trans-[PtCl2(C6H10N2)2], the PtII 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.
