A hexaco-ordinate platinum complex containing four Pt–Sn bonds, one of them to SnII

Abstract

The complex [Pt(CO₃)(SEt₃)] reacts readily with SnR₃H (R =p-MeC₆H₄) in MeOH to give a hexaco-ordinate Pt^IV complex in which the ligands are PEt₃, H (theses two being trans to one another), R₃Sn^IV, R₂Sn^II, and 2 × R₂(MeO)Sn^IV, with the OMe groupe of the last ligands bridging to the R₂Sn^II center; the four Sn and two O atoms lie approximately in a plane, with the Pt atom 0.48Å out of this plane towards the Pet₃ ligand.
