The theoretical data for the half-lantern complexes [{Pt((Formula presented.))(μ- (Formula presented.))}2] [1–3; (Formula presented.) is cyclometalated 2-Ph-benzothiazole; (Formula presented.) is 2-SH-pyridine (1), 2-SH-benzoxazole (2), 2-SH-tetrafluorobenzothiazole (3)] indicate that the Pt⋅⋅⋅Pt orbital interaction increases the nucleophilicity of the outer d (Formula presented.) orbitals to provide assembly with electrophilic species. Complexes 1–3 were co-crystallized with bifunctional halogen bonding (XB) donors to give adducts (1–3)2⋅(1,4-diiodotetrafluorobenzene) and infinite polymeric [1⋅1,1′-diiodoperfluorodiphenyl]n. X-ray crystallography revealed that the supramolecular assembly is achieved through (Aryl)I⋅⋅⋅d (Formula presented.) [PtII] XBs between iodine σ-holes and lone pairs of the positively charged (PtII)2 centers acting as nucleophilic sites. The polymer includes a curved linear chain ⋅⋅⋅Pt2⋅⋅⋅I(areneF)I⋅⋅⋅Pt2⋅⋅⋅ involving XB between iodine atoms of the perfluoroarene linkers and (PtII)2 moieties. The 195Pt NMR, UV/Vis, and CV studies indicate that XB is preserved in CH(D)2Cl2 solutions.
