چکیده
In the title compound, C(5)H(6)N(5) (+)·C(4)H(6)N(3)O(+)·SO(4) (2-), the adeninium (AdH(+)) and cytosinium (CytH(+)) cations and sulfate dianion are involved in a three-dimensional hydrogen-bonding network with four different modes, viz. AdH(+)⋯AdH(+), AdH(+)⋯CytH(+), AdH(+)⋯SO(4) (2-) and CytH(+)⋯SO(4) (2-). The adeninium cations form N-H⋯N dimers through the Hoogsteen faces, generating a characteristic R(2) (2)(10) motif. This AdH(+)⋯AdH(+) hydrogen bond in combination with AdH(+)⋯CytH(+ )H-bonds leads to two-dimensional cationic ribbons parallel to the a axis. The sulfate anions inter-link the ribbons into a three-dimensional hydrogen-bonding network and thus reinforce the crystal structure.

Bis(adeninium) bis(hydrogensulfate) sulfate
The title compound, 2C5H7N5(2+)·2HSO4(-)·SO4(2-), was synthesized from adenine and sulfuric acid. The asymmetric unit contains two diprotonated adeninium cations, two bis-ulfate anions and one sulfate anion. The crystal structure is stabilized by classical N-H⋯O and O-H⋯O hydrogen bonds, and weak C-H⋯O and C-H⋯N hydrogen bonds, generating a three-dimensional network.

In the title proton-transfer organic salt, C5H6.3N5 (+)·C8H4.7O4 (-)·C3H7NO, the adeninium moiety is protonated at the N atom in the 1-position of the 6-amino-7H-purin-1-ium (adeninium) cation. In the solid state, the second acidic proton of isophthalic acid is partially transferred to the imidazole N atom of the adeninium cation [refined O-H versus N-H ratio = 0.70 (11):0.30 (11)]. Through the...

In the title salt, C(5)H(6)N(5) (+)·C(7)H(8)NO(2) (+)·2ClO(4) (-)·3H(2)O, the 3-carboxy-anilinium and adeninium cations are monoprotonated at the amino group and at a pyrimidine N atom respectively. In the crystal, the components are involved in extensive three-dimensional hydrogen-bonding networks composed of O-H⋯O, N-H⋯O, O-H⋯N, N-H⋯N and C-H⋯O inter-actions. Bifurcated hydrogen bonds are obs...

IN THE TITLE SALT (SYSTEMATIC NAME: 6-amino-9H-purin-1-ium perchlorate), C(5)H(6)N(5) (+)·ClO(4) (-), the adeninium cation is essentially planar, with a maximum deviation of 0.038 (1) Å. The whole of the perchlorate anion is disordered over two sets of sites with an occupancy ratio of 0.589 (13):0.411 (13). In the crystal, the adeninium cations are linked by pairs of N-H⋯N hydrogen bond into in...
