2-Amino-3-nitropyridinium hydrogen selenate
The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·HSeO(4) (-), contains two monoprotonated 2-amino-3-nitro-pyridinium cations and two hydrogen selenate anions which are connected through N-H⋯O and O-H⋯O hydrogen bonds, building chains parallel to the a direction. These chains are further connected to each other by weaker C-H⋯O hydrogen-bonding inter-actions, leading to the formati...
متن کامل2-Amino-5-nitropyridinium hydrogen selenate
There are two cations and two anions in the asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·HSeO(4) (-). In the crystal, there are two independent chains of HSeO(4) (-) anions running along the a axis, linked by O-H⋯O hydrogen bonds. Ribbons of cations linked by N-H⋯O hydrogen bonds run along the b-axis direction, and are further hydrogen bonded to the anions by N-H⋯O and C-H⋯O link...
متن کامل2-Amino-3-nitropyridinium hydrogen oxalate
In the non-centrosymetric title compound, C(5)H(6)N(3)O(2) (+)·C(2)HO(4) (-), the hydrogen oxalate anions form corrugated chains parallel to the c axis, linked by O-H⋯O hydrogen bonds. The 2-amino-3-nitro-pyridinium cations are anchored between theses chains by N-H⋯O and C-H⋯O hydrogen bonds and van der Waals and electrostatic inter-actions, creating a three-dimensional network.
متن کامل4-Benzylpyridinium hydrogen selenate
The structure of the title salt, C(12)H(12)N(+)·HSeO(4) (-), consists of infinite parallel two-dimensional planes built of 4-benzyl-pyridinium and hydrogen selenate ions that are mutually connected by strong O-H⋯O and N-H⋯O hydrogen bonds. There are no contacts other than normal van der Waals inter-actions between the layers.
متن کامل2-Amino-6-nitro-1,3-benzothiazol-3-ium hydrogen sulfate
In the title molecular salt, C(7)H(6)N(3)O(2)S(+)·HSO(4) (-), the 2-amino-6-nitro-1,3-benzothia-zole ring system is essentially planar [mean deviation = 0.0605 (4) Å]. In the crystal, N-H⋯O and O-H⋯O hydrogen-bonding inter-actions result in a layer motif.
