Bowl-shaped and highly inert bis(µ-hydroxo)-platinum(II) dimer

Journal Article


Abstract


  • Steric effects are responsible for the bending in [{Pt-(Me2phen)(μ-OH}2]2+ (Me2phen = 2,9-dimethyl-1,10-phenanthroline). The large hinge angle is not expected on the basis of electronic effects alone, since hydroxo bridges and terminal nitrogen donors should lead to planar structures. Unexpected is the markedly increased stability against bridge-cleavage reactions, which could be relevant for the mechanism of reactions catalyzed by PtII and PdII complexes in aqueous medium. A structural study on the bridge-cleavage product [Pt-(Me2phen)(thiourea)2]2+ reveals strong distortions.
