A series of Pt(II) complexes with 2-alkylsubstituted pyridines display planar chirality due to the influence of the pyridine substituent, which enhances the rotational barrier around the Pt–N bond generating a couple of enantiomers. The chiral conformation is also stabilized by the presence of an axial Pt⋅⋅⋅H-C interaction.
