摘要 在THF中,1,5-二甲基-2,4-二-(2,6-二异丙基苯基)-2-异戊烯基钠(L2,6-iPrNa)与YbCl3反应制得YbL2,6-iPrCl2·2THF(1);1在THF中于55℃经Na/K还原合成了一个新型的含有三氯桥的混价双核配合物——(YbL2,6-iPr)2(μ-Cl)3·2THF(2),其结构经IR,X-射线单晶衍射和元素分析表征。2属单斜晶系,空间群C2/c,晶胞参数a=49.823(7),b=12.574 9(15),c=22.368(3),β=102.974(4)°,Z=8,R1=0.064 5,R2=0.138 6。 YbL2,6-iPrCl2 · 2THF(1) was prepared by the reaction of L2,6-iPrNa { L2,6-iPr =[(2,6-iPr-C6H3-NC(Me)] 2CH} with anhydrous YbCl3 in THF.A novle divalent β-diketiminatoytterbium complex containing triple chloride bridge,(YbL2,6-iPr)2(μ-Cl)3 · 2THF(2),was synthesized by the reduction of 1 using Na/K as the reducing agent at 55 ℃ in THF.The structure of 2 was characterized by IR,X-ray single crystal diffraction and element analysis.2 belongs to monoclinic,space group C2/c with a =49.823(7) (A),b =12.574 9(15) (A),c=22.368(3) (A),β=102.974(4)°,Z=8,R1 =0.0645,R2 =0.138 6.
