Abstract
In this paper, we report the quantitative synthesis of the first Pt-silene -complex and its unusual interaction with benzene molecule in the solid state, revealed by X-ray crystallography. Thus, three platinum complexes dock on one benzene molecule via weak van der Waals-type interactions with the benzene hydrogens. The cyclopropane nature of the complex was confirmed by 29Si NMR spectroscopy and molecular structure. Also, an unusual situation in 31P NMR was observed, in which two phosphorus atoms with different chemical environments have similar chemical shifts but different values of J-coupling with platinum.
