Syntheses, structural studies, photoelectron spectra and density functional theory calculations of the "pseudo" tetraphospha-metallocenes [M(eta-P2C3Bu(t)3)(2)], (M = Ni, Pd, Pt).

ABSTRACT

Syntheses and structural characterization of the complexes [M(eta-P(2)C(3)Bu(t)(3))(2)], (M = Ni, Pd, Pt) are described. The nickel compound has an 18-electron [Ni(eta(5)-P(2)C(3)Bu(t)(3))(eta(3)-P(2)C(3)Bu(t)(3))] structure, whereas the palladium and platinum compounds both have a 16-electron [M(eta(3)-P(2)C(3)Bu(t)(3))(2)] structure (M = Pd, Pt).The electronic structure is examined and discussed using both photoelectron spectroscopy and DFT calculations.
