Abstract: Crystals of the title compound, C18H30N6·2H2O, are composed of units of diimidazo[c,h][1,6]diazecine and two water molecules. The asymmetric unit contains one half-molecule of diazecine and one uncoordinated water molecule in a general position. The complete ten-membered heterocycle is generated by an inversion center.The organic residue and water molecules form a two-dimensional hydrogen-bonded network. The 1,6-diazecine ring shows a chair conformation, with angles and distances in normal ranges.
