چکیده
In the title mol-ecular salt, C(11)H(17)N(2) (+)·Cl(-), the piperazin-1-ium ring adopts a chair conformation with the aromatic ring in a pseudo-equatorial orientation. The dihedral angle between the benzene ring and the mean plane of the piperazin-1-ium ring is 51.22 (6)°. In the crystal, N-H⋯Cl hydrogen bonds link the mol-ecules into chains propagating in [100]. Weak C-H⋯π inter-actions also ocur.

In the title compound, [CuCl(3)(C(6)H(16)N(3))]·H(2)O, the copper(II) ion is five-coordinated by two N atoms from the bidentate 4-(2-amino-ethyl)piperazin-1-ium cation and three chloride ions in a distorted square-pyramidal environment. Inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds build up an intricate three-dimensional network.

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 (...
