The synthesis and structural characterization of four new trimethylplatinum(IV) iodide complexes of 2,2′‐bipyridine ligands {[PtMe 3 (4,4′‐Clbipy)I] ( 1 ), [PtMe 3 (4,4′‐Brbipy)I] ( 2 ), [PtMe 3 (4,4′‐CNbipy)I] ( 3 ) and [PtMe 3 (4,4′‐NO 2 bipy)I] ( 4 )} are reported. The 1 H NMR spectra of the complexes reveal the presence of two chemically distinct methyl groups in the complexes. X‐ray crystal structures of complexes 1 – 4 show that the platinum metal center in each of the complexes form distorted octahedral structure being surrounded by methyl groups, bipyridine ligand, and iodine atom. Furthermore, the crystal packing study shows that self‐assembly of the complexes are governed by weak hydrogen bonding and other non‐covalent interactions such as π ··· π, halogen ··· π and C–H ··· π interactions. Complex 1 exhibits infinite one‐dimensional zigzag chain structure and other three complexes form infinite ladder type structures.
