The coordination chemistry of the N-substituted arylamido ligands [N(R)(C6H3R'2-2,6)] [R = SiMe3, R' = Me (L1); R = CH2But, R' = Pri (L2)] toward FeII and CoII ions was studied. The monoamido complexes [M(L1)(Cl)(tmeda)] [M = Fe (1), Co (2)] react readily with MeLi, affording the mononuclear, paramagnetic iron(II) and cobalt(II) methyl-arylamido complexes [M(L1)(Me)(tmeda)] [M = Fe (3), Co (4)]. Treatment of 2:1 [Li(L2)(THF)2]/FeCl2 affords the unusual two-coordinate iron(II) bis(arylamide) [Fe(L2)2] (5).
研究了N-取代芳基酰胺配体[N(R)(C6H3R'2-2,6)] [R = SiMe3，R' = Me (L1)；R = CH2But，R' = Pri (L2)]与FeII和CoII离子的配位化学。单酰胺配合物[M(L1)(Cl)(tmeda)] [M = Fe (1)，Co (2)]与MeLi容易反应，得到单核、顺磁性的铁(II)和钴(II)甲基芳基酰胺配合物[M(L1)(Me)(tmeda)] [M = Fe (3)，Co (4)]。用2:1的[Li(L2)(THF)2]/FeCl2处理得到不寻常的二配位铁(II)双(芳基酰胺)[Fe(L2)2] (5)。
