Platinum–Tin Bonded Complexes, Including a Structural Analysis of the Octahedral Tris(pyrazol-1-yl)borate Complex Pt(SnMe3)Me2{(pz)3BH-N,N',N"}

Abstract

The platinum(II) complex K[PtMe₂ {(pz)₃BH-N,N′}] reacts with SnCl₂Me₂ to form Pt(SnClMe₂)Me₂- {(pz)₃BH-N,N′ ,N″} ([(pz)₃BH]^–=tris(pyrazol-1-yl)borate). The closely related complex Pt(SnMe₃)Me₂- { (pz)₃BH-N,N′ ,N″ } has distorted octahedral geometry for platinum with Pt–Sn 2·5727(8) Å . The Pt–N distance trans to the SnMe₃ group [2·237(7) Å] is longer than those trans to the Me groups [2·127(7) and 2·131(6) Å], indicating for the trimethylstannyl group a trans influence which is higher than that for the methyl group.
