Abstract
The title compound, C14H2ON3O4+.C6H2N3O7-.H2O, contains a 15-membered macrocycle which has two ether O atoms, two pairs of amide N and O ato ms, and an amine N atom as potential donor atoms. The macrocycle has u ndergone protonation at the amine N atom. The picrate ion interacts th rough its phenolic O atom with the NH2 group via an N-H ... O hydrogen bond. The water molecule is linked in an endocyclic manner to the mac rocyclic ring through both the amide groups by an O ... H-N hydrogen b ond. The ether O atoms do not participate in any hydrogen-bonding inte ractions. The water molecule is also intermolecularly linked to one sy mmetry-related nitro group O atom of the picrate and to one amide O at om.
