Structure and magnetism of a tetrahedral uranium(iii) β-diketiminate complex†
Abstract
We describe the functionalisation of the previously reported uranium(III) β-diketiminate complex (BDI)UI2(THF)2 (1) with one and two equivalents of a sterically demanding 2,6-diisopropylphenolate ligand (ODipp) leading to the formation of two heteroleptic complexes: [(BDI)UI(ODipp)]2 (2) and (BDI)U(ODipp)2 (3). The latter is a rare example of a tetrahedral uranium(III) complex, and it shows single-molecule magnet behaviour.
