1-Benzyl-2-dimethylamino-3-methyl-3,4,5,6-tetrahydropyrimidin-1-ium bromide
In the title molecular salt, C(14)H(22)N(3) (+)·Br(-), the ring incorporating the guanidinium grouping exhibits a half-chair conformation and the dihedral angle between the N-C-N and C-C-C planes is 55.0 (3)°. The C-N bond lengths in the central CN(3) unit are 1.333 (4), 1.338 (3) and 1.341 (4) Å, indicating partial double-bond character. The central C atom is bonded to the three N atoms in a n...

In the title compound, C(11)H(12)BrN(2) (+)·Br(-), the imidazole and phenyl rings are nearly perpendicular, making a dihedral angle of 87.71 (7)°. The crystal structure is stabilized by non-classical inter-molecular C-H⋯Br hydrogen bonds and inversion-related mol-ecules are linked through π-π inter-actions between the imidazole ring systems [centroid-centroid distance = 3.472 (6) Å].

Isolated guanidinium ions and tetra-phenyl-borate ions are present in the crystal structure of the title compound, C(11)H(22)N(3)O(2) (+)·C(24)H(20)B(-). In the guanidinium ion, the dihedral angle between the N/C/N and C/C/C planes being 49.9 (1)°. The six-membered ring exhibits a half-chair conformation. The C-N bond lengths in the cation range between 1.3335 (16) and 1.3552 (16) Å, indicating...
متن کامل3-Allyl-1-(2-cyanobenzyl)-2-methylbenzimidazol-3-ium bromide
In the title compound, C(19)H(18)N(3) (+)·Br(-), both the allyl and cyano-phenyl groups are approximately perpendicular to the central benzimidazole unit, making dihedral angles of 89.7 (2) and 85.09 (13)°, respectively. The crystal packing is dominated by C-H⋯Br inter-actions, with each anion inter-acting with five neighboring cations.
متن کامل3-Allyl-1-(3-cyanophenylmethylene)-2-methyl-1H-benzoimidazol-3-ium bromide monohydrate
In the title compound, C(19)H(18)N(3) (+)·Br(-)·H(2)O, the dihedral angle between the allyl group and the imidazole ring is 89.59 (14)°, while the dihedral angle between the cyanophenyl ring and the imidazole ring is 78.72 (7)°. O-H⋯Br hydrogen bonds form an infinite chain in the c-axis direction and C-H⋯Br and C-H⋯O inter-actions expand this chain into an infinite three-dimensional network.
