چکیده
The title compound, C(12)H(18)N(8) (2+)·2NO(3) (-)·2H(2)O, was synthesized unexpectedly from 3-amino-1-methyl-1,4,5,6-tetra-hydro-pyrrolo-[3,4-c]pyrazol-5-ium chloride and cerium(IV) ammonium nitrate. The cation has a crystallographically imposed centre of symmetry. In the crystal, the ions and water mol-ecules are linked via O-H⋯N, N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network.

The title compound, C(18)H(20)N(2)O(2), was prepared by Mannich-type reaction of phenol, ethane-1,2-diamine and formaldehyde. The heterocyclic rings adopt half-chair conformations. The acyclic methyl-ene groups attached to the N atoms are in an axial position. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into dimers. These dimers are further connected via C-H⋯π contacts.
