介绍了有关尿素、硫脲、硒脲的晶体结构以及它们的典型管状包合物的结构化学特征.综述了包括近期发表的新颖的层状硫脲包合物,含主体-客体、客体-客体间氢键的尿素包合物,以及在不同条件下影响尿素类管状包合物晶体中主客体间作用力的因素等,有关尿素及其衍生物为主体分子的包合物的研究发展现状. The crystal structures of urea, thiourea and selenourea as well as the structural chemical characteristics of their typical tubular inclusions are reviewed, including the recently published novel layered thiourea clathrates, including host-guest, guest-guest Hydrogen bonds between the urea inclusion compound, as well as under different conditions affect the tubular body of objects in the urea-like clathrin interaction factors, the main body of the urea and its derivatives clathrate research and development of the status quo.
