2-Amino-pyrimidinium picrate.

ABSTRACT: The geometric parameters of the title compound, C(4)H(6)N(3) (+)·C(6)H(2)N(3)O(7) (-), are in the usual ranges. While two nitro groups are almost coplanar with the aromatic picrate ring [dihedral angles 3.0?(2) and 4.4?(3)°], the third is significantly twisted out of this plane [dihedral angle 46.47?(8)°]. Anions and cations are connected via N-H?O hydrogen bonds. The mol-ecules crystallize in planes parallel to (11).

2-Amino-pyridinium picrate.

Project description:In the title compound, C(5)H(7)N(2) (+)·C(6)H(2)N(3)O(7) (-), there are two crystallographically independent cations and anions (A and B) in the asymmetric unit. In both picrate anions, one of the nitro groups lies in the plane of the benzene ring [r.m.s. deviations = 0.014?(2) and 0.014?(2)?Å for anions A and B, respectively] and the other two are twisted away by 39.0?(2) and 18.8?(2)° in A, and 18.2?(1) and 2.5?(2)° in B. In the crystal, the cations and anions are linked by inter-molecular N-H?O and C-H?O hydrogen bonds, forming a two-dimensional network.

3-Amino-pyridinium picrate.

Project description:During the formation of the title compound, C(5)H(7)N(2) (+)·C(6)H(2)N(3)O(7) (-), a phenolic proton is transferred to the pyridine N atom.

These layers are connected by weak π-π stacking inter-actions between symmetry-related pyridine and picric benzene rings with a centroid-centroid distance of 3.758 (2) Å, forming a three-dimensional network.

2-Amino-pyrimidinium dihydrogen phosphate monohydrate.

Project description:In the title compound, C(4)H(6)N(3) (+)·H(2)O(4)P(-)·H(2)O, the pyrimidin-ium ring is essentially planar, with an r.m.s. deviation of 0.0016 Å. In the structure, pairs of symmetry-related anions are connected into centrosymmetric clusters via strong O-H⋯O hydrogen bonds forming six-membered rings with an R(2) (2)(6) motif. These clusters are inter-connected via water mol-ecules through OW-H⋯O hydrogen bonds, building an infinite layer parallel to the ab plane. Moreover, infinite chains of 2-amino-pyrimidinium cations spread along the a-axis direction. These chains are connected to the inorganic layer through N-H⋯O, C-H⋯O and C-H⋯N hydrogen bonds, which, together with electrostatic and van der Waals inter-actions, contribute to the cohesion and stability of the network in the crystal structure.

Project description:In the crystal structure of the title compound, C(4)H(6)N(3) (+)·HSO(4) (-), hydrogen sulfate anions self-assemble through O-H?O hydrogen bonds, forming chains along the b axis, while the cations form centrosymmetric pairs via N-H?N hydrogen bonds.
