Crystal structure of 2,4-diamino-7-(hydroxymethyl)pteridin-1-ium nitrate
In the crystal of the title mol-ecular salt, C7H9N6O(+)·NO3 (-), the cations and anions are linked via N-H⋯O and O-H⋯O hydrogen bonds, forming sheets parallel to (100). Within the sheets there are numerous hydrogen-bonding ring motifs.

In the title salt, C(4)H(8)N(5) (+)·NO(3) (-), a ring N atom of 2,6-diamino-4-methyl-triazine is protonated. Each anion is connected to three neighbouring cations by multiple N-H⋯O hydrogen bonds which, together with N-H⋯N contacts, generate a layer structure.

In the cation of the title salt, C9H20NO(+)·CF3O3S(-), the six-membered heterocyclic ring displays a chair conformation. In the crystal, centrosymmetric pairs of cations and anions are linked by N-H⋯O and O-H⋯O hydrogen bonds to form rings with a R 4 (4)(14) graph-set motif.

In the title salt, C(9)H(8)NO(+)·NO(3) (-), the quinoline ring system is essentially planar with a maximum deviation of 0.043 (1) Å. In the crystal, an R(2) (2)(7) ring motif is formed by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds between the cation and the anion. In addition, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link the two ions, generating an R(2) (2)(8) ring motif. These sets ...
متن کامل2-Cyanoquinolin-1-ium nitrate
A proton is transferred from the nitric acid to the N atom of 2-cyano-quinoline during crystallization, resulting in the formation of the title salt, C(10)H(7)N(2) (+)·NO(3) (-). The quinolinium ring system is approximately planar, with a maximum deviation of 0.013 (3) Å. In the crystal, a very asymmetric bifurcated N-H⋯(O,O) hydrogen bond to two O atoms of an adjacent nitrate anion occurs, gen...
