Unprecedented heterocyclization allowed the preparation of a novel class of cationic 1,2,4-selenadiazoles in remarkably high yields. Cationic 1,2,4-selenadiazoles form supramolecular dimers in the crystal via SeMIDLINE HORIZONTAL ELLIPSISN chalcogen bonding, which was studied theoretically.Chemistry, Inorganic & NuclearChemistrychlorideNovel cationic 1,2,4-selenadiazoles: synthesis via addition of 2-pyridylselenyl halides to unactivated nitriles, structures and four-center SeMIDLINE HORIZONTAL ELLIPSISN contactstext::journal::journal article::research article
