Abstract
A zwitter-ionic salt 2-piperidinyl-4-dinitromethyl-1,3,5-triazin(1H,5H)-6-one is studied by the single crystal X-ray analysis. The crystals are monoclinic: a = 11.526(1) Å, b = 9.211(1) Å, c = 12.182(1) Å; β = 110.69(1)°, V = 1209.9(2) Å3, space group P21/n; Z = 4, ρcalc = 1.560 g/cm3. The transformation of the dinitromethyl fragment conformation, the conjugation of one of nitrogroups with the 1,3,5-triazine ring, and an intramolecular hydrogen bond are revealed. The 1,3,5-triazine cycle is strongly distorted due to lactam-lactim tautomerism.
