2-(苯亚胺基次甲基)吲哚铕胺基配合物[η1∶η1-2-(C6H5NH=CH)C8H5N]2Eu[N(Si Me3)2](1)与二芳基取代甲脒(2,6-R2C6H3N=CHNH(C6H3R2-2,6)(R=iPr(2),Me(3))经过配体交换反应,分别得到了含吲哚基脒基铕配合物[η1∶η1-2-(C6H5NH=CH)C8H5N]Eu[(η3-2,6-iPr2C6H3)N=CHN(C6H3iPr2-2,6)][N(Si Me3)2](4)和含脒基的稀土铕配合物[(η3-2,6-Me2C6H3)N=CHN(C6H3Me2-2,6)]2Eu[N(Si Me3)2](5)。结果表明,脒基的位阻显著影响了吲哚基稀土金属胺基配合物与二芳基取代甲脒的配体交换反应。配合物4和5通过IR、元素分析和X射线单晶衍射分析进行了表征。
(1) is reacted with a diaryl-substituted amino group [η1: η1-2- (C6H5NH = CH) C8H5N] 2Eu [N (SiMe3) 2] The ligand exchange reaction of the amidine (2,6-R2C6H3N = CHNH (C6H3R2-2,6) (R = iPr (2), Me (3) (4) and an amidino group-containing rare earth (η) - (C6H3NP═CH2) Europium complex [(η3-2,6-Me2C6H3) N = CHN (C6H3Me2-2,6)] 2Eu [N (SiMe3) 2] (5) The results show that the steric hindrance of the amidino group significantly affects the indole Ligand exchange reaction of two rare-earth metal amine complexes with diaryl-substituted formamidines. Complexes 4 and 5 were characterized by IR, elemental analysis and single crystal X-ray diffraction.
