Europium(II) and ytterbium(II) aryloxide chemistry: synthesis and crystal structure of [Eu(OC6H3But2-2,6)2(THF)3]·0.75C7H8 and [Yb(OC6H3But2-2,6)2(NCMe)4]
摘要:
The reactions of europium and ytterbium with 2,6-di-tert-butylphenol were studied by the metal vapour synthesis technique and by dissolution in liquid ammonia. The lanthanide complexes [Eu(OC6H3Bu2'-2,6)(2)(THF)(3)].0.75C(7)H(8) I and [Yb(OC6H3Bu2'-2,6)(2)(NCMe)(4)] 2 were synthesized and characterized by X-ray diffraction studies.
