Two new air- and water-stable Pt(II) metallosupramolecular complexes based on ambidentate ligands have been designed, synthesized and fully characterized. The structure of complexes has been determined by various analytical techniques including NMR spectroscopy and TOF-MS. Additionally, the single crystal structure of 2 was determined by X-ray diffraction. The catalytic activity of these complexes in hydrosilylation has been investigated, establishing that both have similar high activity and selectivity within a broad scope of structurally distinct olefins and hydrosilanes.
