用光学和X射线衍射方法研究了含15-冠-5片段的2-苯乙烯基苯并噻唑与碱土金属离子、质子、Ag+和Hg ~（2+）的配合物形成。该化合物能够通过两个中心的参与结合金属阳离子：冠醚部分和杂环部分。碱土金属阳离子与分子的大环部分形成络合物。在Ba ~（2+）存在的情况下，形成了一个强的夹心复合物。质子与分子的杂环片段的N原子配位。Ag+和Hg 2+阳离子与分子的两个中心结合：冠醚片段和杂环残基。
The complex formation of 2-styrylbenzothiazole containing a 15-crown-5 ether fragment with alkaline earth metal cations, proton, Ag+ and Hg2+ was studied by optical and X-ray diffraction methods. The compound is able to bind the metal cations through the participation of two centers: the crown ether moiety and the heterocyclic part. The alkaline earth metal cations form complexes with the macrocyclic part of the molecule. The formation of a strong sandwich complex was found in the case of Ba2+. The proton coordinates with the N atom of the heterocyclic fragment of the molecule. The Ag+ and Hg2+ cations bind with both centers of the molecule: the crown ether fragment and the heterocyclic residue.
