چکیده
In the crystal structure of the title proton-transfer compound, CH(6)N(3)O(+)·C(7)H(4)NO(4) (-), O-H⋯O and N-H⋯O hydrogen bonds are formed respectively between the cations and the anions, each component affording a supra-molecular chain along the c axis. The cation and anion chains are further linked by N-H⋯O and N-H⋯N hydrogen bonds. A π-π inter-action is also observed between the pyridine rings; the inter-planar separation and the centroid-centroid distance are 3.3425 (6) and 4.6256 (11) Å, respectively.

Different cation-protonation patterns in molecular salts of unsymmetrical dimethyhydrazine: C2H9N2·Br and C2H9N2·H2PO3
We describe the syntheses and crystal structures of two mol-ecular salts containing the 1,1-di-methyl-hydrazinium cation, namely 1,1-di-methyl-hydrazin-1-ium bromide, C2H9N2 (+)·Br(-), (I), and 2,2-di-methyl-hydrazin-1-ium di-hydrogen phosphite, C2H9N2 (+)·H2PO3 (-), (II). In (I), the cation is protonated at the methyl-ated N atom and N-H⋯Br hydrogen bonds generate [010] chains in the crystal. ...

The hydrazinium residue in the cation of the title salt, C(6)H(10)N(3)O(2)S(+)·Cl(-), is twisted out of the plane of the benzene ring to which it is attached [N-N-C-C torsion angle = 25.9 (2)°] and the amino group is almost perpendicular to the benzene ring [N-S-C-C torsion angle = 88.71 (16)°]. In the crystal, the cations are linked by N-H⋯O hydrogen bonds and π-π inter-actions [ring centroid ...

In the title hydrated salt, C(16)H(13)ClN(3) (+)·Cl(-)·2H(2)O, a small twist is evident in the cation so that the chloro-benzene ring is not coplanar with the central hydrazinyl group [the N-C-C-C torsion angle = -4.8 (12)°]. The conformation about the imine N=C bond [1.284 (10) Å] is E. The components of the structure are connected into a three-dimensional architecture via O-H⋯O, O-H⋯Cl and N-...

In the title compound, [Cu(C21H19N6O2)Cl], the Cu(II) atom is in a slightly distorted square-planar coordination involving two O atoms from the pyrazolone rings [Cu-O = 2.088 (10) and 1.975 (10) Å], an N atom of the azo group [Cu-N = 2.048 (13) Å] and a chloride anion [Cu-Cl = 2.183 (5) Å]. The organic anions act as tridentate chelating ligands. The mol-ecules stack in columns along the c axis.
