Abstract
5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene (1) (C urtis macrocycle) was synthesized and studied by X-ray diffraction and NMR spectroscopy. In addition, a product of its decomposition 5,7,7-trimethyl-2 ,3,6,7-tetrahydro-1,4-diazepine (2) was found and identified by NMR spectro scopy. The X-ray structure of 1 . H2O and 1.2 HBr . 2 H2O is given.
