Abstract : We have prepared the hydrates of oxygen, nitrogen, carbon monoxide and air in their regions of stability at high pressure. Except for carbon monoxide hydrate, whose structure is not yet confirmed, the X-ray and-or neutron powder diffraction patterns show their structures to be von Stackelberg-s type II. Clathrate hydrates of methylcyclohexane, pinacolone and t-butyl methyl ether with H2S or Xe as help gas, were identified from the 2H NMR spectra of deuterated or partially deuterated guest molecules and from 129Xe chemical shieldings as being distinct from type II hydrates. On the basis of neutron and X-ray powder diffraction patterns, it is suggested that the new clathrate hydrates are isostructural with the clathrasil dodecasil-1H.
