The synthesis and crystal structure of the title PtII complex, [Pt(C23H16N)Cl(CH3CN)], based on the C,N-chelating 2,4,6-triphenylpyridine as the primary ligand, is described. The central PtII atom is in a distorted square-planar coordination environment. In the crystal, molecules are arranged via a metallophilic interaction between platinum atoms with a Pt...Pt contact of 7.052 (2) Å. In addition, a π–π interaction occurs.
