What is Polythreading of 1-D sawtooth into 3-D ths net in the strong hydrogen-bonded supramolecular structure of 2-(1H-tetrazol-5-yl)pyrazine hemihydrate about?

Crystallization of tetrazole compound, 2-(1H-tetrazol-5-yl)pyrazine (TZP), from water gives rise to the 2:1 hydrate, TZP•(TZP•H 2 O), with entangled structure involving two-dimensionally distinct strong hydrogen-bonded motifs of 1-D sawtooth chain and 3-D ths net (also called ThSi 2 , (10, 3)-b net). In the former, TZP molecules link each other in an end-to-end mode by NAH,N(pyrazine) hydrogen bonds (C(6) synthon), while in the latter, both TZP and water molecules assemble through OAH,N(tetrazol), OAH,N(pyrazine) and NAH,O hydrogen bonds with each acting as a 3-connected node. There also exist weak hydrogen bonds of the CAH,N(tetrazol) between such 1-D chains and the 3-D net, and between adjacent chains, respectively. This result represents a rare example of hydrogenbonded polythreading organic structure, and further exploits the using of tetrazole compound in hydrogen-bonded crystal engineering.
