Abstract
AbstractRoom temperature reaction of 2‐vinylpyridine ligand (L, 2 equiv.) with the known dimethylplatinum(II) complex cis,cis‐[Me2Pt(µ‐SMe2)2PtMe2], A, provided a novel dimeric platinum(II) complex [PtMe2(µ2‐η1:η2‐2‐vpy)]2, 2, by displacement of the dimethyl sulfide (SMe2) ligands with the nitrogen atom and the olefinic double bond donors of 2‐vpy. The single crystal structure of complex 2 reveals a distorted square‐planar geometry around platinum centers. Two L groups in this complex act as bridging ligands between platinum centers, displaying a short Pt⋅⋅⋅Pt interaction with unique orientation in a head‐to‐tail (HT) arrangement. Complex 2 was not stable in dimethyl sulfoxide (dmso) solution, and through C‐H bond activation produced methane and cyclometalated complex [PtMe(η1:η1‐2‐vpy)(dmso)], 1.
