The last paper from Dr. Kerry Barnett's dissertation has been published in Inorganic Chemistry in collaboration with the Dixon Group. This paper provides a detailed structural analysis of the palladium complexes of trineopentylphosphine ligands using computational and experimental data. The highly flexible trineopentylphosphine ligand adopts a very sterically demanding conformation when coordinated to 1- or 2-coordinate palladium centers. Unusually, this very sterically demanding ligand is highly pyramidalized due to the low back-side strain of the neopentyl groups. When coordinated to a 3- or 4-coordinate palladium center, trineopentylphoshine adopts a less sterically demanding conformation.
