Abstract

The mol­ecular structure of Sn(NHMes)4 is defined by a central tin(IV) atom that is coordinated by four NHMes groups in a distorted tetra­hedral arrangement.

Transamination of Sn(NMe2)4 with H2NMes (Mes is 2,4,6-tri­methyl­phenyl, C9H11) led to the formation of the title compound, [Sn(C9H12N)4] or Sn(NHMes)4, which crystallizes in the tetra­gonal space group P

21 c, with four formula units per unit cell. The mol­ecular structure consists of a central tin(IV) atom, which is surrounded by four NHMes groups. Sn(NHMes)4 possesses crystallographically imposed
symmetry. The SnN4 coordination polyhedron is best described as a compressed bis­phenoid.

四-顺式(2,4,6-三甲基苯胺基)锡(IV)。
Sn(NMe2)4 与 H2NMes(Mes 为 2,4,6-三甲基苯基,C9H11)发生转化反应,生成了标题化合物 [Sn(C9H12N)4] 或 Sn(NHMes)4,该化合物在 P 21 c 四元空间群中结晶,每个单胞有四个式单元。其分子结构由一个中心锡(IV)原子和四个 NHMes 基团组成。Sn(NHMes)4 具有晶体学上的对称性。SnN4 配位多面体最适合描述为一个压缩的双正二面体。
