Reactions of 2,6-disubstituted 1-oxa-4-thia-3,5-diazine 4,4-dioxides with substituted cyanamides in aromatic solvents (benzene, toluene, chlorobenzene, benzonitrile) furnished stable complexes including 1-oxa-4-thia-3,5-diazine4,4-dioxide, symmetric triazine, and solvent (or no solvent) in a ratio 2 : 2 : 1. The molecules involved in the complexes are joined by intramolecular forces into a unified energetically favorable supramolecular system.
在芳香族溶剂(苯、甲苯、氯苯、苯甲腈)中,2,6-二取代 1-氧杂-4-噻-3,5-二嗪-4,4-二氧化物与取代氰酰胺发生反应,生成了稳定的复合物,其中包括 1-氧杂-4-噻-3,5-二嗪-4,4-二氧化物、对称三嗪和溶剂(或无溶剂),比例为 2 : 2 : 1。络合物中的分子通过分子内力结合成一个统一的、对能量有利的超分子体系。
