Photoelectron spectroscopy and electronic structure of the hexaphosphatitanocene [Ti(eta(5)-P3C2Bu2t)(2)]

Autor: F. Geoffery N. Cloke, Jennifer C. Green, John F. Nixon, John R. Hanks, James L. Suter

Density functional calculations on [Ti(η5-P3C2But2)2] gave estimates of structural parameters in excellent agreement with experiment and predicted a diamagnetic ground state as has been found. Back donation from the metal to the π LUMO of the ring

Treatment of MI3 ( M = Sc, Y, Tm, and U) with three equivalents of KP3C2Bu2t in refluxing toluene led to the corresponding monomeric, formally eight coordinate, complexes [M(eta(5)-P3C2Bu2t)(2)(eta(2)-P3C2Bu2t)] in moderate yields. In the solid state

The unusual trigonal prismatic structure of tris(butadiene)molybdenum, reported in 1975 by Skell, has been revisited by extensive quantum chemical calculations and by a low-temperature single-crystal X-ray diffraction study. While a trigonal prismati

Stabilization of low-oxidation-state early transition-metal complexes bearing 1,2,4-triphosphacyclopentadienyl ligands: structure of [[Sc(P3C2tBu2)2]2]; ScII or mixed oxidation state?

ScII or mixed oxidation state ScIII/ScI? Reduction of the homoleptic ScIII complex [Sc(P3C2tBu2)3] allows access to the subvalent [{Sc(P3C2tBu2])2}2] complex (see picture), in which the metal centers are formally bivalent. DFT calculations support fo
