N2 - The X-ray crystal structure of [La(Odpp)3(THF)2]·THF (Odpp = OC6H3Ph2-2,6), prepared by reaction of lanthanum metal, bis(pentafluorophenyl)mercury and 2,6-diphenylphenol in THF, shows distorted trigonal-bipyramidal stereochemistry for lanthanum. A phenolate oxygen [LaO 2.25(1) Å] and a THF oxygen [LaO 2.68(2) Å] occupy apical positions [OLaO 165.9(4)°], whilst two phenolate oxygens [LaO 2.25(1), 2.234(9) Å] and a THF oxygen [LaO 2.52(1) Å] occupy trigonal positions [OLaO 122.1(4), 124.8(5), 96.5(6)°]. The apical LaO(THF) distance is exceptionally and unexpectedly long. Unit cell data for [Nd(Odpp)3(THF)2]·THF suggest that it is isostructural with the lanthanum compound.
