2,3,9,10,15,16-Hexaaza­tetra­cyclo­[6.6.2.0^4,16.0^11,15]hexa­decane dihydrate

The four six-membered fused rings in the title compound, C₁₀H₂₀N₆·2H₂O, adopt chair conformations; the H atoms of the four secondary N atoms occupy axial positions. Hydrogen bonds of the types N—H...N, N—H...O and O—H...N link the organic and water mol­ecules into a three-dimensional network.
