The sterically demanding N-heterocyclic carbene ITr (N,N′-bis(triphenylmethyl)imidazolylidene) was employed for the preparation of novel trigonal zinc(II) complexes of the type [ZnX2(ITr)] [X = Cl (1), Br (2), and I (3)], for which the low coordination mode was confirmed in both solution and solid state. Because of the atypical coordination geometry, the reactivity of 1–3 was studied in detail using
空间要求高的N -杂环卡宾 ITr ( N , N '-双(三苯基甲基)咪唑基) 用于制备 [ZnX 2 (ITr)] [X = Cl ( 1 ) 类型的新型三方锌 (II) 配合物、Br( 2 )和I( 3 )],其低配位模式在溶液和固态中均得到证实。由于非典型的配位几何结构,使用部分或彻底的卤化物交换和卤化物提取反应详细研究了1-3的反应性,以获取 [ZnLCl(ITr)] [L = 咔唑盐 ( 4 ), 3,6-二叔-丁基咔唑酯 ( 5 )、吩恶嗪 ( 6 ) 和吩噻嗪 ( 7 )]、[Zn(bdt)(ITr)](bdt = 苯-1,2-二硫醇盐)( 8 ) 和阳离子 [Zn(μ 2 -X)(ITr)] 2 [B(C 6 F 5 ) 4 ] 2 [X = Cl ( 9 )、Br ( 10 ) 和 I ( 11 )],所有这些均已分离并进行了结构表征。重要的是,对于所有配合物4-11 ,Zn
