Popis:	The structure of 5,7,12,14-tetramethyl-1,4,8,11-tetra-azacyclotetradecane dihydrate, C 14 H 32 N 4 .2H 2 O, contains molecules of 5SR,7RS,12RS,14SR-tetramethyl-1,4,8,11 -tetraazacyclotetradecane (which are centrosymmetric) and 5SR,7RS,12SR,14RS-tetramethyl-1,4,8,11-tetraazacyclotetradecane, with different macrocycle conformations and different configurations of the four chiral C atoms. The crystal structure is stabilized by hydrogen bonds.
