Unprecedented higher stability of E-than Z-olefin complexes of platinum(II). Molecular structures of the η3-methally(triphenylphosphine)(Z-and E-but-2-ene)-platinum(II) cation
Abstract
The CC bond of Z-but-2-ene in one of the title complexes lies almost in the co-ordination plane, while that of the corresponding E-but-2-ene complex, which unprecedentedly is more stable in solution than the former, forms and angle of 67° with the plane.
