Abstract
The 30 non-H atoms in title dihydrazine compound, C(20)H(16)N(6)O(4)center dot 2H(2)O, are close to coplanar, the r.m.s. deviation for these atoms being 0.096 angstrom. The conformation about each of the C=N bonds is E, and the molecule has non-crystallographic 2/m symmetry. The presence of O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonding leads to a three-dimensional network in the crystal structure. A highly disordered solvent molecule is present within a molecular cavity defined by the organic and water molecules. Its contribution to the electron density was removed from the observed data in the final cycles of refinement and the formula, molecular weight and density are given without taking into account the contribution of the solvent molecule.
