Solid state structures of five new molecular complexes of SbI3 with Py have been determined by single crystal X‐ray structural analysis. In all complexes, all antimony atoms adopt a pseudo‐octahedral coordination geometry, which is completed by additional Sb⋅⋅⋅I contacts shorter than sum of van der Waals radii, with I−Sb⋅⋅⋅I angles close to 180°.

通过单晶X射线结构分析确定了SbI 3与Py的五个新分子复合物的固态结构。在所有络合物中,所有
锑原子都采用伪八面体配位几何结构,这是通过比Van der Waals半径总和短的Sb⋅⋅⋅I接触完成的,I-Sb⋅⋅⋅I的角度接近180°。对静电势,轨道相互作用和拓扑分析的分析表明,这些接触是由于存在Sb⋅⋅⋅I碳素原键而引起的。报道了SbI 3的三个光原性键的第一个例子。
