2-Amino-4-phenyl-4H,10H-1,3,5-triazino[1,2-a]benzimidazol-3-ium chloride
2-Guanidinobenzimidazole condenses with benzaldehyde in the presence of hydro-chloric acid to form 2-amino-3,4-dihydro-4-phenyl-1,3,5-triazino[1,2-a]benzimidazole, which was isolated as its hydro-chloride, C(15)H(14)N(5) (+)·Cl(-). The positive charge of the cation is formally placed on the double-bonded N atom of the dihydro-triazine ring. The six-membered dihydro-triazine that is fused with t...

In the cation of the title salt, C(11)H(12)IN(4) (+)·Cl(-), the two aromatic rings are oriented to each other at 9.3 (2)°. In the crystal, the two independent Cl(-) anions lie on twofold rotation axes. N-H⋯Cl hydrogen bonds between the cations and anions generate a supra-molecular layer parallel to (010).

In the crystal structure of the title compound, C(7)H(11)N(2)O(2)S(+)·Cl(-)·H(2)O, the cations, anions and water mol-ecules are linked by inter-molecular N-H⋯O, N-H⋯Cl, O-H⋯O and O-H⋯Cl hydrogen bonds, forming layers stacked along [20].

The title compound, C(14)H(18)ClN(2)S(+)·Cl(-), crystallizes with two formula units in the asymmetric unit. The dihedral angles between the mean planes of the chloro-phenyl and thia-zole rings are 87.8 (2) and 88.0 (2)° in the two independent mol-ecules. In the crystal, the anions and cations are connected by N-H⋯Cl hydrogen bonds.

In the cation of the title compound, C(7)H(7)N(4)O(2) (+)·Cl(-), the benzimidazole ring system is planar with a maximum deviation of -0.019 (3) Å. In the crystal structure, C-H⋯Cl, N-H⋯Cl, and N-H⋯Cl inter-actions link the mol-ecules into a two-dimensional network. π-π contacts between benzimidazole rings [centroid-centroid distances = 3.928 (1) and 3.587 (1) Å] may further stabilize the struct...
