TlCl与[LiN（Me）Ar（Mes）2]（2）[Ar（Mes）2 = C（6）H（3）-2，6-（C（6）H（2）-2，4，6-Me（3））（2）]在Et（2）O中反应生成酰胺铊TlN（Me）Ar（Mes）2（1）。X-射线衍射数据表明它是单体结构，平均Tl-N距离为2.364（3）埃。三联苯取代基的侧接均三甲苯环也存在Tl-芳烃途径[Tl-质心= 3.026（2）Angiotensin（avg）]。DFT计算表明，这种相互作用是弱的，基本上支持一个协调的铊。与单体TlAr（Trip）2（Trip = C（6）H（2）-2，4，6-Pr（i）（3））相比，1的电子光谱发生了蓝移。
Reaction of TlCl and [LiN(Me)Ar(Mes)2](2) [Ar(Mes)2 = C(6)H(3)-2,6-(C(6)H(2)-2,4,6-Me(3))(2)] in Et(2)O generated the thallium amide, TlN(Me)Ar(Mes)2 (1). X-ray data showed that it has a monomeric structure with an average Tl-N distance of 2.364(3) Angstroms. There was also a Tl-arene approach [Tl-centroid = 3.026(2) Angstroms (avg)] to a flanking mesityl ring from the terphenyl substituent. DFT calculations showed that this interaction is weak and supported essentially one coordination for thallium. The electronic spectrum of 1 is hypsochromically shifted in comparison to the monomeric TlAr(Trip)2 (Trip = C(6)H(2)-2,4,6-Pr(i)(3)).
