Metal-Involving Bifurcated Halogen Bonding with Iodide and Platinum(II) Center.

ABSTRACT: The cocrystallization of trans-[PtI₂(NCR)₂] (R = NMe₂1, NEt₂2, Ph 3, o-ClC₆H₄4) with iodine and iodoform gave the crystalline adducts 1∙4I₂, 2∙2CHI₃, 3∙2CHI₃, and 4∙4I₂, whose structures were studied by single-crystal X-ray diffractometry (XRD). In the structures, apart from the rather predictable C-H⋯I hydrogen bonds (HBs) and I-I⋯I or C-I⋯I halogen bonds (XBs) with the iodide ligands, we identified bifurcated I-I⋯(I-Pt) and C-I⋯(I-Pt) metal-involving XBs, where the platinum center and iodide ligands function as simultaneous XB acceptors toward σ-holes of I atoms in I₂ or CHI₃.
