Noncovalent interactions, such as halogen bonding (HaB) and π-stacking, play a pivotal role in directing supramolecular assemblies and tuning photophysical properties. Herein, we report the synthesis, X-ray structural characterization, and photophysical properties of cocrystals and host:guest adducts formed by iodopentafluorobenzene (G) with three distinct Pt(II) complexes (1–3). The cocrystals exhibit a combination of short I···Pt halogen bonds and π-hole···Pt interactions in the solid state, highlighting the dual role of the Pt(II) center as a halogen bond acceptor and a π-stacking participant. Interestingly, an enhancement in emission intensity is observed for complexes 1·G and 2·G upon mixing of 1 or 2 with G in a chloroform solution, attributed to synergistic σ-hole···[dz2-PtII] interactions that reduce the flexibility of the square-planar complex and the double heavy atom effect. These results emphasize the potential of host:guest interactions as a strategy for enhancing luminescence efficiency and open new avenues for designing functional materials for sensing and optoelectronic applications.

We report the synthesis of novel ionic heteronuclear Pt(II)–Ag(I) complexes derived from Pt(NCN)-C≡CR precursors (R = aryl), where Ag+ ions coordinate to the acetylene groups. The photophysical invest...
