Amino(5-{2-[amino(iminio)methyl]hydrazin-1-yl}-3,5-dimethyl-4,5-dihydro-1H-pyrazol-1-yl)methaniminium dinitrate
The reaction of aqueous solutions of amino-guanidine hydrogennitrate and acetyl-acetone produces the title pyrazole salt, C(7)H(18)N(8) (2+)·2NO(3) (-). The crystal structure is stabilized by a complex N-H⋯O hydrogen-bonding network. The difference in the engagement of the two nitrate anions in hydrogen bonding is reflected in the variation of the corresponding N-O bond lengths.

There are two independent mol-ecules in the asymmetric unit of the title compound, C21H21N5O2. In each mol-ecule, the indolizine ring system is essentially planar, with r.m.s. deviations of 0.030 and 0.028 Å. The dihedral angles between the indolizine ring system and the pyrazole rings are 54.7 (3) and 8.6 (3)° in one mol-ecule and 54.4 (3) and 6.6 (3)° in the other. In the crystal, weak C-H⋯O ...

In the title compound, C(24)H(19)N(3)O, the pyrazoline ring adopts an envelope conformation with the C atom linking to the pyridine ring as the flap. The mean plane of the pyrazoline ring makes dihedral angles of 85.54 (4) and 81.66 (3)° with the pyridine ring and the anthracene ring system, respectively. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds. In addition, weak π-π inter...

In the title compound, C14H16N6O2, the dihedral angles formed by the mean plane of the acetohydrazide group [maximum deviation 0.0629 (12) Å] with the pyrazole and pyridine rings are 81.62 (6) and 38.38 (4)° respectively. In the crystal, mol-ecules are connected by N-H⋯O and O-H⋯N hydrogen bonds into supra-molecular chains extending parallel to the c-axis direction.

In the mol-ecule of the title compound, C(12)H(15)N(3)O(2), the pyrazole ring is oriented at a dihedral angle of 49.64 (6)° with respect to the benzene ring. Intra-molecular O-H⋯O, N-H⋯O and C-H⋯O inter-actions result in the formation of a trifurcated hydrogen bond. In the crystal structure, inter-molecular N-H⋯O and O-H⋯N hydrogen bonds link the mol-ecules, forming a network structure.
