Figure 3 Crystal structure of the title compound showing the H-bond network (dashed lines) involving the NH+ groupings, the water molecules and the perchlorate anions. Only one orientation for the disordered water molecule (O2W is the oxygen atom) is shown. Symmetry codes: i) −x + 1; y, −z + ; iii)-x + ,y − 1/2,-z + ; iv)x − 1/2, y − , z. |
