Abstract
Although Structure H hydrate has been studied intensively for a number of years, its detailed crystal structure has remained unknown. Single crystal X-ray diffraction was used to determine the structure of 2,2-dimethylpentane·5(Xe, H2S)·34H2O hydrate. The hexagonal unit cell, space group P6/mmm with z=1, has the following parameters: a = 12.212(2), c = 10.143(2) Å (t = −100°C). Cage geometries and fractional coordinates for the atoms are presented and discussed. Structure H hydrate is only the third hydrate type for which a large number of molecules are suitable as guests.Keywords
