The title compound, C14H20N3O4+ C6H2N3O7−.H2O, contains a 15-membered macrocycle which has two ether O atoms, two pairs of amide N and O atoms, and an amine N atom as potential donor atoms. The macrocycle has undergone protonation at the amine N atom. The picrate ion interacts through its phenolic O atom with the –NH2 group via an N-HO hydrogen bond. The water molecule is linked in an endocyclic manner to the macrocyclic ring through both the amide groups by forming an OH-N hydrogen bond. The ether O atoms do not participate in any hydrogen-bonding interactions. The water molecule is also intermolecularly linked to one symmetry-related nitro group O atom of the picrate and to one amide O atom.
