Abstract In this work we studied transition mechanics of a dynamic hydrogen bond network of water into a stable hydrogen bond network during gas clathrate hydrate formation process. For this purpose, we used Molecular Dynamic simulation methods and a bunch of home-made programs for determining structural properties during transition process. We have found that at certain conditions the network transformation process involves the whole system from the very beginning and could be considered as a collective effect, that results in high speed of hydrate formation.

To compare the structural properties of oxalamide and thiooxalamide groups in the formation of hydrogen bonds suitable for supramolecular assemblies a series of retropeptides was studied. Some of them, having oxalamide bridges, are gelators of organic solvents and water. However, retropeptides with oxygen replaced by the sp 2 sulfur have not exhibited such properties. The crystal structures of the two title compounds are homostructural, i.e. they have similar packing arrangements. The monothio compound crystallizes in the orthorhombic space group P212121 with two molecules in the asymmetric unit arranged in a hydrogen-bond network with an approximate 41 axis along the crystallographic b axis. However, the dithio and dioxo analogues crystallize in the tetragonal space group P41 with similar packing patterns and hydrogen-bonding systems arranged in agreement with a crystallographic 41 axis. Thus, these two analogues are isostructural having closely related hydrogen-bonding patterns in spite of the different size and polarity of oxygen and sulfur which serve as the proton acceptors.
