Complexes of the Lanthanides, I. - Solvent-Free Alkoxide Complexes of Neodymium and Dysprosium. Crystal and Molecular Structure of trans-Bis(acetonitrile)tris(tri-tert-butylmethoxy)neodymium The first lanthanide complex 3a is obtained from the sterically demanding silanol (tC4H9)3SiOH (, „silox“, 1a) and Nd-[N{Si(CH3)3}2]3 (2a). Similarly, the bulky alcohols, „tritox-H“, tri-tert-butylmethanol (1b), and, „ditox-H“, di-tert-butylmethanol (1c), react with 2a to give the corresponding alkoxide complexes Nd(tritox)3 (3b) and [Nd(ditox)3]2 (3c), respectively. Under the same conditions Dy[N{Si(CH3)3}2]3 (2b) yields the homoleptic ditox derivative 6. The new complexes are all very soluble in aliphatic hydrocarbons. They show a very different thermal stability as, for example, expressed in their sublimation behaviour.
