Halogen chalcogen and hydrogen bonding in organoiodine cocrystals of heterocyclic thio­nes: imidazolidine-2-thione 2-mercaptobenzimidazole 2-mercapto-5-methyl­benzimidazole 2-mercaptobenzoxazole and 2-mercaptobenzo­thia­zole

摘要

A series of 18 cocrystals were obtained through the combination of the heterocyclic mol­ecules imidazolidine-2-thione, 2-mercaptobenzimidazole, 2-mercapto-5-methyl­benz­imidazole, 2-mercaptobenzoxazole, and 2-mercaptobenzo­thia­zole with the common halogen-bond donors 1,2-, 1,3-, and 1,4-di­iodo­tetra­fluoro­benzene, 1,3,5-tri­fluoro­tri­iodo­benzene, and tetra­iodo­ethyl­ene. A rich series of hydrogen-, halogen-, and chalcogen-bonding inter­actions were observed.
