The synthesis of 1,4,7,10,13- BenzopentaoxacycIopentadecin-2,3,5,6,8,9,11,12-octahydro-15,16-dinitro is achieved by the nitration of 1,4,7,10,13-benzopentaoxacyclodecin-2,3,5,6,8,9,11,12-octahydro. This compound is characterized by spectroscopic technics, IR, UV, ¹H-NMR, ¹³C-NMR, mass spectrometry and by XR diffraction. A monocrystal from the product was selected and its crystal structure solved. The solid crystallizes in the monoclinic system with space group P2₁/n and a := 11,7443 (3) ; b = 8,5135 (3) ; c = 17,4845(5) Å ; β = 108,324 (1 )° and Z = 4. The cavities of the macrocycle are rigidified by five intramolecular hydrogen bonds, whereas six hydrogen bonds between a molecule and three near neighbors ensure crystal cohesion.
