Abstract

The selenium adducts of germa- and stanna-closo-dodecaborate can coordinate at platinum via the selenium atom and result in the products [Pt(dppp)(Se–TB11H11)2]2− (T = Ge, Sn) (dppp = 1,3-bis(diphenylphosphino)propane). The monomeric tin compound [Pt(dppp)(Se–SnB11H11)2]2− is converted to a dimeric complex [Pt2(dppp)2(μ2,μ′2-η2-Se2SnB11H11)]. The new compounds were characterized by NMR spectroscopy in solution (1H, 11B, 13C, 31P, 77Se, 119Sn, 195Pt), elemental analysis and single crystal X-ray diffraction.
