Acta Crystallogr E Crystallogr Commun. 2015 May 20;71(Pt 6):644-6. doi: 10.1107/S2056989015009196. eCollection 2015 Jun 1.


In the title complex, [PtCl2(C5H11N)(C6H6N2O2)], the Pt(II) metal atom displays a slightly distorted trans-PtN2Cl2 square-planar coordination geometry. The dihedral angle between the mean plane of the benzene and piperidine rings is 89.03 (3)°. In the crystal structure, inversion dimers are formed via N-H⋯Cl hydrogen-bond inter-actions, resulting in chains parallel to the [001] direction. The benzene rings within the chains show π-π stacking inter-actions [centroid-to-centroid distances of 3.801 (3) Å] and neighbouring chains inter-act via N-H⋯O hydrogen bonds.

Keywords: crystal structure; hydrogen bonding; trans-platinum(II) complexes.
