of the structures of Nitron, Nitron(S) and Nitron(S)Me, together with hypothetical versions in which the phenyl substituents are replaced by hydrogen, indicates that these changes are in accord with bond order differences predicted by natural bond orbital methods. A similar evaluation of the thione groups of Nitron(S) and Nitron(S)Me indicates that the C–S bonds are composed of both covalent and ionic
摘要 通过单晶X射线衍射确定了两种衍生自Nitron的1,2,4-三唑硫酮,即Nitron(S)和Nitron(S)Me的分子结构。与 Nitron 的结构比较表明,硫酮的形成伴随着与硫酮基团相反的 5 元环内的 C-N 键的缩短,以及环外 C-N 键的延长。对 Nitron、Nitron(S) 和 Nitron(S)Me 的结构以及其中苯基取代基被氢取代的假设版本的分析表明,这些变化与通过自然键轨道方法预测的键序差异一致。
