This study presents a new uncharged platinum(II) complex with a pyrazolyliodonium ligand, which features an exceptionally large σ-hole on the iodine atom. Single-crystal X-ray diffraction analysis reveals the structure of the [LPtCl3]·2DMF complex, highlighting two types of intermolecular halogen bonds: a C−I⋯O bond with DMF and C−I⋯Cl bonds with the platinum complex. Quantum chemical calculations confirm the high positive electrostatic potential on the iodine σ-hole, demonstrating its significant halogen bond donor ability.
