Iso‐Tellurazole N‐Oxides Assemble Adaptively Folded Macrocyclic Dodecamers
Chemistry – A European Journal, EarlyView.Te…O Chalcogen bonding links twelve molecules into a ring that wraps itself around molecular guests. ABSTRACT Self‐assembled macrocyclic dodecamers were found in the crystals of new pseudo‐polymorphs of iso‐tellurazole N‐oxides. These structures are formed by molecules connected by NTe…O chalcogen bonds and are folded in a pattern that defines 89–153 ...
