Transition from cage clathrate to filled ice: the structure of methane hydrate III.

J S Loveday1, R J Nelmes, M Guthrie, D D Klug, J S Tse.   

Abstract

The structure of a new methane hydrate has been solved at 3 GPa from neutron and x-ray powder diffraction data. It is a dihydrate in which a 3D H-bonded network of water molecules forms channels surrounding the methane molecules. The network is closely related to that of ice-Ih and the methane-water system appears to be the first in which a cage clathrate hydrate is transformed into an ice-related hydrate (a "filled ice").
