Complexes Containing a Phenol–Platinum(II) Hydrogen Bond: Synthons for Supramolecular Self‐Assembly and Precursors for Hydridoplatinum(IV) Complexes

摘要

> The cycloneophylplatinum(II) complexes [Pt(CH ₂ CMe ₂ C ₆ H ₄ )(κ 2 ‐NN′‐2‐C ₅ H ₄ NCH ₂ ‐NH‐R], R = 2‐C ₆ H ₄ OH, 1 ; R = 3‐C ₆ H ₄ OH, 2 ; R = 4‐C ₆ H ₄ OH, 3 , and [Pt(CH ₂ CMe ₂ C ₆ H ₄ )(κ 2 ‐NN′‐2‐C ₅ H ₄ NCH=N‐2‐C ₆ H ₄ OH)], 4 , are reported. The structures of 1 and 4 each contain an intramolecular OH ·· Pt hydrogen bond, while complex 3 contains an intermolecular OH ·· Pt hydrogen bond and forms a new type of supramolecular polymer. In contrast, the complex [PtCl ₂ (κ 2 ‐NN′‐2‐C ₅ H ₄ NCH=N‐2‐C ₆ H ₄ OH)], 5 , forms a dimer through intermolecular OH ·· ClPt hydrogen bonding. Reaction of complex 4 with HCl or HBr occurs by oxidative addition to give hydridoplatinum(IV) complexes [PtHX(CH ₂ CMe ₂ C
