摘要

Graphs of 20-vertex polyhedra-cavities in gas hydrates and particular high-symmetry clusters of tetrahedrally coordinated structures are determined as incidence graphs of Desargues subconfigurations 103, 10 3 3 , and 10 3 4 . It is shown that symmetrically possible mutual transformations of rods of gas hydrates and tetrahedrally coordinated diamond-like structures correspond to conjugate subconfigurations of these configurations. It is established that the relations obtained determine on the symmetry level the mechanisms of incorporation of guest molecules into polyhedra-cavities of gas hydrates and their escape from these cavities. The corresponding structural models of mutual transformations of gas hydrates and tetrahedrally coordinated structures are implemented by the transfer of a minimum number of hydrogen bonds.
