Clathrate hydrates of some amines.

A crystallographic study of some alkylamine hydrates establishes that these are polyhedral clathrate hy drates. While the simpler alkylamines form hydrates with water structures re lated to those of the gas hydrates or the alkylonium salt hydrates, the di ethylamine and tert-butylamine hydrates have water frameworks forming cages which have not previously been ob served in the clathrate hydrates.
