Abstract

The reduction of Dpp-BIAN with neodymium metal in the presence of equimolar amounts of iodine gave the neodymium complex with acenaphthene-1,2-diimine ligand in the dianion form, [(Dpp-BIAN)NdI(DME)₂] (I) (Dpp-BIAN is (1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene, DME is dimethoxyethane). The treatment of the complexes [(Dpp-BIAN)LnI(Solv)_n] (Solv is ether solvent), (Ln = Nd, Dy, Tm) with solutions of thex [Dpp-BIANK₂] molecular iodine resulted in the formation of bis-ligand ate-complexes [(Dpp-BIAN)₂Nd][K(Et₂O)_2.62(THF)_0.38]Et₂O (II), [(Dpp-BIAN)₂Dy][K(DME)₄](DME)_0.28 (III), and [(Dpp-BIAN)₂Tm][K(Et₂O)₃]Et₂O (IV). The reaction of [(Dpp-BIAN)NdI(DME)₂] with lithium trimethylsilylamide gave the product [(Dpp-BIAN)₂Nd][Li(DME)(Et₂O)₂] (V). The molecular structure of complexes I–V was established by X-ray diffraction analysis (CCDC no. 2409375 (I), 2409376 (II), 2409377 (III), 2409378 (IV), 2409379 (V)).

[(Dpp-BIAN)LnI(Solv)x]配合物（Ln = Nd, Dy, Tm）及其还原反应

在等摩尔量的碘存在下，用金属钕还原Dpp-BIAN，得到了与苊-1,2-二亚胺配体以双离子形式的钕配合物，[(Dpp-BIAN)NdI(DME)2] (I) (Dpp-BIAN是（1,2-二[（2,6-二异丙基苯基）亚胺]苊，DME是二甲氧基乙烷）。配合物[(Dpp-BIAN)LnI(Solv)n] （Solv为醚溶剂），（Ln = Nd, Dy, Tm）与[Dpp-BIANK2]分子碘溶液处理后形成双配体配合物[(Dpp-BIAN)2Nd][K(Et2O)2.62(THF)0.38]Et2O (II), [(Dpp-BIAN)2Dy][K(DME)4](DME)0.28 (III)]和[(Dpp-BIAN)2Tm][K(Et2O)3]Et2O （IV）。[(Dpp-BIAN)NdI(DME)2]与三甲基硅酰胺锂反应得到[(Dpp-BIAN)2][Li(DME)(Et2O)2] (V)。配合物I-V的分子结构通过x射线衍射分析得到。2409375 (i), 2409376 (ii), 2409377 （iii), 2409378 (iv), 2409379 (v))）。
