TiCl_3·3THF与Salen-Na_2在THF中反应得到标题化合物。在混合溶剂中培养出单晶,用X射线衍射法测定了结构。晶体属正交晶系,空间群为D~(16)_(2h)—P_(bnm),a=7.458(2),b=14.075(6),c=18.752(2),z=4,经最小二乘法修正最后偏离因子R=0.086,R_w=0.066。探讨了用TiCl_3·3THF直接与Salen-H_2反应只能得到四价钛的稳定配合物的原因。考察了此配合物与二氧化碳及烷基铝的作用。
TiCl 3 · 3THF reacted with Salen-Na 2 in THF to give the title compound. Single crystals were grown in a mixed solvent and the structure was determined by X-ray diffractometry. The crystal belongs to the orthorhombic system with a space group of D ~ (16) _ (2h) -P bnm, a = 7.458 (2), b = 14.075 (6), c = 18.752 (2) The least square method was used to correct the final deviation factor R = 0.086, R_w = 0.066. The reason why TiCl 3 · 3THF reacted directly with Salen-H 2 to form stable complexes of tetravalent titanium was discussed. The effect of this complex on carbon dioxide and aluminum alkyls was investigated.
