metal vapour synthesis technique and by dissolution in liquid ammonia. The lanthanide complexes [Eu (OC6H3But2-2, 6) 2 (THF) 3]· 0.75 C7H81 and [Yb (OC6H3But2-2, 6) 2 (NCMe) 4] 2 were synthesized and characterized by X-ray diffraction studies.
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(OC6H3But2-2,6)2(THF)3]·0.75C7H81 and [Yb(OC6H3But2-2,6)2(NCMe)4] 2 were synthesized and characterized by X-ray diffraction studies.
