Silver(I) complexes of 2,3,5,6-tetrakis(methylsulfanyl)pyridine (tmp), [Ag3(tmp)4][ClO4]3·C3H6O 1 and [Ag2(tmp)2][C2F5CO2]2 2, have been prepared and their molecular structures determined by X-ray crystallography. In both complexes two tmp ligands are positioned face to face by two Ag atoms and form a box structure. In 1 three types of silver(I) ion are present depending on the co-ordination numbers
2,3,5,6-四(甲基硫烷基)吡啶(tmp),[Ag 3(tmp)4 ] [ClO 4 ] 3 ·C 3 H 6 O 1和[Ag 2(tmp)的银(I)配合物制备了2 ] [C 2 F 5 CO 2 ] 2 2,并通过X射线晶体学确定了它们的分子结构。在这两种络合物中,两个tmp配体被两个Ag原子面对面放置,并形成盒形结构。在1种三种类型的银(我离子的存在取决于配位数。一个tmp分子充当盒结构之间的桥梁,导致磁带排列。吡啶环之间的π-π堆积形成了二维网络。2,相比之下,银(我)离子具有具有三个硫醚S原子一个三角平面的环境; 每个tmp都充当桥接金属中心的配体,从而形成二维薄片。
