We report a new lattice structure of the ionic clathrate hydrate of tetra-n-butylammonium bromide induced by guest CO<inf>2</inf> molecules, which is found to provide high CO<inf>2</inf> storage capacity. The structure was characterized by a set of methods, including single crystal X-ray diffraction, NMR, and MD simulations.Peer reviewed: YesNRC publication: Ye
