In the title complex, [Ag(NO3)(C10H9N3)4], the nitrate ligand is found to be disordered over two sets of positions, with occupancy factors of 0.473 (5) and 0.527 (5). The AgI ion is located in a square-pyramidal coordination environment formed by four N atoms from four bis­(pyridin-2-yl)amine ligands and one O atom from a nitrate ligand. Weak inter­actions between the AgI ions and the nitrate anions acting in a monodentate mode [Ag...O = 2.791 (13) and 2.816 (9) Å for the major component of the nitrate ligand, and 2.865 (8) and 2.837 (8) Å for the minor component] link the complex mol­ecules into a chain along [001]. N—H...O hydrogen bonds are observed.

In the title compound, [PtCl2(C13H21N5)]·0.5CH3NO2, the PtII atom is coordinated in a slightly distorted square-planar geometry by two Cl atoms and two N atoms of the bidentate ligand. The (1,3,5-tri­aza­penta­diene)PtII metalla ring is slightly bent and does not conjugate with the aromatic ring. In the crystal, N—H...Cl hydrogen bonds link the complex mol­ecules, forming chains along [001]. The nitromethane solvent molecule shows half-occupancy and is disordered over two sets of sites about an inversion centre.

In the cation of the title salt, C10H10N3+·C6H2N3O7, the pyridine and pyridinium rings are linked by an intra­molecular N—H...N hydrogen bond and are approximately coplanar, with a dihedral angle between their planes of 4.24 (6)°. In the crystal, the cations and anions are linked through N—H...O hydrogen bonds, forming supra­molecular chains propagating along the c-axis direction. π–π stacking is observed between neighbouring chains, the centroid–centroid distances being 3.7638 (11) (between pyridinium rings) and 3.5331 (11) Å (between benzene rings).
