Figure 3
The hydrogen-bonding inter­actions involving the disordered N2—H4 and OW1—H6 groups are divided into two symmetrically related sets (top and bottom). The diagram also shows the hydrogen-bonding inter­actions involving the protonated NH3 groups. [Symmetry codes: (i) 1 − x, y, [{1\over 2}] − z; (ii) x, 1 − y, −[{1\over 2}] + z; (iii) x, 1 + y, z; (iv) [{1\over 2}] − x, −[{1\over 2}] + y, [{1\over 2}] − z; (v) x, 1 − y, [{1\over 2}] + z; (vi) 1 − x, −y, 1 − z; (vii) 1 − x, −1 + y, [{1\over 2}] − z; (viii) x, −y, [{1\over 2}] + z; (ix) 1 − x, 1 − y, 1 − z; (x) [{1\over 2}] + x, [{1\over 2}] − y, [{1\over 2}] + z.]
