Bis(2,6-diamino-4-chloropyrimidin-1-ium) fumarate
In the title salt, 2C4H6ClN4(+)·C4H2O4(2-), the complete fumarate dianion is generated by crystallographic inversion symmetry. The cation is essentially planar, with a maximum deviation of 0.018 (1) Å. In the anion, the carboxyl-ate group is twisted slightly away from the attached plane, the dihedral angle between the carboxyl-ate and (E)-but-2-ene planes being 12.78 (13)°. In the crystal, the ...

In the crystal structure of the title compound, C(4)H(7)N(4)O(+)·Cl(-)·2H(2)O, adjacent cations are connected to one another through N-H⋯O hydrogen bonds, forming infinite chains along the b axis. These chains are further hydrogen bonded to the chloride anions and water mol-ecules, resulting in a three-dimensional network. The pyrimidine rings of adjacent mol-ecules are arranged in an anti-para...

The title compound, C(4)H(8)N(5) (+)·C(2)HO(4) (-), was obtained from the reaction of oxalic acid and 2,4-diamino-6-methyl-1,3,5-triazine. The protonated triazine ring is essentially planar with a maximum deviation of 0.035 (1) Å, but the hydrogen oxalate anion is less planar, with a maximum deviation of 0.131 (1) Å for both carbonyl O atoms. In the crystal, the ions are linked by inter-molecul...

In the title compound, C(4)H(8)N(5) (+)·Cl(-), a two-dimensional layer packing network is observed in which every chloride anion links three adjacent 2,4-diamino-6-methyl-1,3,5-triazin-1-ium cations by N-H⋯Cl hydrogen-bonding inter-actions, forming 12-membered and eight-membered hydrogen-bonded rings with graph-set motifs R(4) (4)(12) and R(3) (3)(8), respectively. In addition, N-H⋯N hydrogen b...

In the crystal structure of the title salt, C(4)H(8)N(5) (+)·BF(4) (-), centrosymmetrically related cations undergo base pairing via a pair of N-H⋯N hydrogen bonds, forming an R(2) (2)(8) ring motif. The cations and anions inter-act via N-H⋯F hydrogen bonds, generating supra-molecular layers parallel to ([Formula: see text]20), which are in turn linked into a three-dimensional network, forming ...
