Abstract: Ionic clathrate hydrates formed from aqueous solutions of tetra-n-butylammonium bromide in the course of rapid cooling (30Kmin⁻¹) to −35°C have been examined. An earlier unknown metastable hydrate of cubic structure I was obtained from the solutions with concentrations from 3.2 to 4.8 mol%.

Keywords: ionic clathrate hydrate, tetra-n-butylammonium bromide, cubic structure I, metastable state, powder X-ray diffraction.
