Two oxazane macrocycles.
Cox, Philip J.; Kong Thoo Lin, Paul
Abstract
The 20-membered ring in 1,7,11,17-tetraoxa-2,6,12,16-tetraazacycloeicosane tetrahydrochloride, C12H32N4O44+·4Cl-, adopts an endo conformation, while the 18-membered ring in 1,6,10,15-tetraoxa-2,5,11,14-tetraazacyclooctadecane tetrahydrochloride, C10H28N4O44+·4Cl-, lies about an inversion centre and adopts a symmetrical conformation. In the crystal structures of both compounds, the cations and chloride anions are linked by N-H...Cl hydrogen bonds into planar sheets of molecules; the sheets are linked into three-dimensional networks via C-H...Cl hydrogen bonds.
