Periodate anions as a halogen bond donor: formation of anion⋯anion dimers and other adducts
Miriam Calabrese, Andrea Pizzi, Andrea Daolio, Antonio Frontera, Giuseppe Resnati
Abstract
Single crystal X-ray analyses show that iodine in pyridinium periodates acts as a halogen bond (HaB) donor forming short and almost linear contacts with neutral and anionic electron donors. A combination of QTAIM and NCIplot computational tools proves the attractive nature of these contacts.
