Trichloromethyl thiocyanate, CCl3SCN, was structurally studied in both the gas and crystal phases by means of gas electron diffraction (GED) and single‐crystal X‐ray diffraction (XRD), respectively. Both experimental studies and quantum chemical calculations indicate a staggered orientation of the CCl3 group relative to the SCN group. This conclusion is supported by the similarity of the C−SCN bond
分别通过气相电子衍射(GED)和单晶X射线衍射(XRD)在气相和结晶相中研究了三氯甲基硫氰酸盐CCl 3 SCN。实验研究和量子化学计算均表明CCl 3基团相对于SCN基团的方向错开。这一结论是由C-SCN键长的相似性,所述的支持抗CH的-结构2 ClSCN(Berrueta Martinez等的PHY。化学式化学物理2015,17,15805-15812)。1气体和晶体CCl的键长和键角相似3SCN结构;然而,晶体结构表现出不同的分子间相互作用。其中包括卤素和硫属元素类型的相互作用,已对其几何结构进行了研究。接近180°的特征C‐Y⋅⋅⋅N角(Y = Cl或S)为分子间分子N⋅⋅⋅Cl和N⋅⋅⋅S中的卤素/硫族元素-碳键上典型的σ-空穴相互作用提供了证据单位。
