Hydrogen bonding in polyamino-polyalcohols: a monohydrated cocrystal of 1,3-di­amino-5-azaniumyl-1,3,5-tri­deoxy-cis-inositol iodide and 1,3,5-tri­amino-1,3,5-tri­deoxy-cis-inositol

C. Neis and K. Hegetschweiler

Synopsis: In a monohydrated cocrystal of 1,3,5-tri­amino-1,3,5-tri­deoxy-cis-inositol and its hydro­iodide salt, the cation, but not the neutral inositol unit, exhibits intra­molecular O-H...O hydrogen bonding. The neutral and cationic inositol entities are each aligned into chains along [001]. In these chains, two O-H...N inter­actions generate a ten-membered ring as the predominant structural motif.

Formula: C6H16N3O3+·I-·C6H15N3O3·H2O
