Square‐Planar Anionic Pt ⁰ Complexes

A T-shaped Pt0 complex with a diphosphine-borane (DPB) ligand was prepared. The Pt→B interaction enhances the electrophilicity of metal and triggers addition Lewis bases to give corresponding tetracoordinate complexes. For first time, anionic complexes are isolated structurally authenticated. X-ray diffraction analyses show [(DPB)PtX]− (X=CN, Cl, Br, I) be square-planar. d10 configuration oxidation state were unambiguously established by photoelectron spectroscopy DFT calculations. coordination acids as Z-type ligands is powerful mean stabilize elusive electron-rich achieve uncommon geometry.
