Bis(pyridin-2-ylmeth-yl)ammonium nitrate.

In the title compound, C12H14N3 (+)·NO3 (-), the mononitrate of protonated bis-(pyridin-2-ylmeth-yl)amine, the least-squares planes defined by the non-H atoms of the two aromatic moieties inter-sect at an angle of 7.91 (6)°. In the crystal, N-H⋯N, N-H⋯O and C-H⋯N hydrogen bonds, as well as C-H⋯O contacts, connect the entities into a three-dimensional network. The shortest centroid-centroid distance between two aromatic systems is 3.7255 (8) Šand is apparent between the two different aromatic moieties.

1,3-Bis(2-meth-oxy-phen-yl)thio-urea.

In the title compound, C(15)H(16)N(2)O(2)S, the N-C(=S) bond lengths are indicative of the presence of amide-type resonance. The dihedral angles between the thio-urea unit and the attached aromatic rings are 59.80 (5) and 73.41 (4)° while the dihedral angle between the rings is 56.83 (4)°. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds occur. An N-H⋯π inter-action is observed for the second amino group. The shortest centroid-centroid distance between two aromatic systems is 4.0958 (8) Å.
