In the title macrocyclic polyamine, C(24)H(38)N(6).5H(2)O, the centrosymmetric polyamine molecules are stacked in rows, and between these molecules there are channels along the a axis. The intermolecular hydrogen bonds formed between the water and polyamine, together with those formed between water molecules, generate an extensive hydrogen-bonding network.
