generated in situ from LH and nBuLi, or with the isolated lithium complex [Li(L1)(OEt2)]2 (for Ln = Yb) in THF afforded the solvent-free homoleptic complexes [Ln(L)3] [Ln = Yb (1a), Er (1b), Sm (1c), Pr (1d), Nd (1e), L = L1; Ln = Yb (2a), Y (2b), Sm (2c), Nd (2d), La (2e), L = L2). With a 2:1 LiL (generated in situ) to LnCl3 molar ratio, the solvent-free heteroleptic complexes [Ln(L)2(μ-Cl)]2 were
用三摩尔当量的 LiL [(L = N-(2-甲氧基苯基)-N-(三甲基甲硅烷基)酰胺 (L1) 或 N-(2-苯氧基苯基)-N-(三甲基甲硅烷基)酰胺 (L2)] 处理 LnCl3,从 LH 和 nBuLi 原位生成,或在 THF 中使用分离的锂配合物 [Li(L1)(OEt2)]2(对于 Ln = Yb)提供无溶剂均配配合物 [Ln(L)3] [Ln = Yb (1a), Er (1b), Sm (1c), Pr (1d), Nd (1e), L = L1; Ln = Yb (2a), Y (2b), Sm (2c), Nd (2d), La (2e), L = L2)。以 2:1 LiL(原位生成)与 LnCl3 摩尔比,获得无溶剂杂配配合物 [Ln(L)2(μ-Cl)]2,L = N,N-二甲基-N'-三甲基甲硅烷基乙烷-1,2-二胺 (en') [Ln = Yb (3a), Er
