[O─I─O]+ Halogen‐Bonded Complexes of Pyridine N‐Oxides

open access: yesAngewandte Chemie, Volume 138, Issue 40, 28 September 2026.
The missing puzzle of 3‐center‐4‐electron halogen‐bonded complexes viz. [O─I─O]+ of pyridine N‐oxides are structurally characterized by x‐ray diffraction. Monodentate N‐oxide O‐atom acts as the halogen bond acceptor. Their solution complexations are characterized by 15N NMR spectroscopy.
