Insight into geometric preferences in uranium(vi) mixed tris(imido) systems†
Abstract
Uranium tris(imido) species have been synthesized using different imido groups in the axial and equatorial positions by treating [(MesPDIMe)U(THF)]2 (1-THF), which is a uranium(IV) dimer that is supported by MesPDIMe tetraanions, with mixed organoazide solutions. While the origin of the geometric preference isn't clear, both steric and electronic factors are likely at play.
