5-triazapentadienes [N(C3F7)C(Mes)N}2]H and [N(C3F7)C(Dipp)N}2]H (where Mes = 2,4,6-Me3C6H2; Dipp = 2,6-Pri2C6H3) with n-BuLi in hexane, followed by the crystallization from hexane–THF mixture afforded the corresponding lithium 1,3,5-triazapentadienyl complexes as their THF solvates. X-Ray crystallographic analyses revealed that [N(C3F7)C(Mes)N}2]Li(THF)2 and [N(C3F7)C(Dipp)N}2]Li(THF) are monomeric
1,3,5-三氮杂戊二烯类[N (C 3 F 7)C(Mes)N} 2 ] H和[N (C 3 F 7)C(Dipp)N} 2 ] H(其中Mes = 2,4,6-Me 3 C 6 H 2; Dipp = 2,6-Pr i 2 C 6 H 3),其中n -BuLi正己烷,然后从 正己烷-THF混合物作为THF溶剂化物提供相应的1,3,5-三氮杂戊二烯基锂配合物。X射线晶体分析表明,[N (C 3 F 7)C(Mes)N} 2 ] Li(THF)2和[N (C 3 F 7)C(Dipp)N} 2 ] Li(THF) )是固态的单体。[N (C 3 F 7)C(Mes)N} 2 ] Li(THF)2具有四坐标的锂中心,具有扭曲的四面体几何形状,并且具有船形的C 2 N 3 Li金属环。[N (C 3 F 7)C(Dipp)N} 2] Li(THF)具有三配位的锂原子和平面的U形C 2
