چکیده
The title compound, C(15)H(16)ClN(5)O, contains two mol-ecules, A and B, in the asymmetric unit, in which the dihedral angles between the terminal aromatic rings are 42.41 (17) and 45.77 (18)°. The central six-membered ring in both mol-ecules has a chair conformation with equatorial substituents. In the crystal, mol-ecules are linked into [100] C(4) chains of alternating A and B mol-ecules by N-H⋯O hydrogen bonds.

The title salts, C8H13N4 (+)·Cl(-), (I), and C8H13N4 (+)·NO3 (-), (II), contain linked pyridinium-piperazine heterocycles. In both salts, the piperazine ring adopts a chair conformation with protonation at the N atom not linked to the other ring. In the crystal of (I), weak N-H⋯Cl inter-actions are observed, leading to zigzag chains along [100]. In the crystal of (II), both H atoms on the NH2 (...
