5-Methyl-2-pyridone
The crystal structure of the title compound, C(6)H(7)NO, is stabilized by inter-molecular N-H⋯O hydrogen bonds, resulting in inversion dimers. The structure is further consolidated by weak C-H⋯O hydrogen bonds.
متن کاملCrystal structures of the two salts 2-methyl-1H-imidazol-3-ium nitrate–2-methyl-1H-imidazole (1/1) and 2-methyl-1H-imidazol-3-ium nitrate
The title salts, C4H7N2 (+)·NO3 (-)·C4H6N2, (I), and C4H7N2 (+)·NO3 (-), (II), were obtained from solutions containing 2-methyl-imidazole and nitric acid in different concentrations. In the crystal structure of salt (I), one of the -NH H atoms of the imidazole ring shows half-occupancy, hence only every second mol-ecule is in its cationic form. The nitrate anion in this structure lies on a twof...
متن کامل1-Methyl-3-phenylquinoxalin-2(1H)-one
The phenyl substituents in both independent mol-ecules of the title compound, C(15)H(12)N(2)O, are twisted with respect to the quinoxaline system [dihedral angles = 19.3 (1) and 30.4 (1)°].
متن کامل3-Methyl-1-propargylquinoxalin-2(1H)-one
The ten-membered fused ring of the title compound, C(12)H(10)N(2)O, is essentially planar in the two independent mol-ecules of the asymmetric unit (r.m.s. deviations = 0.012 and 0.015 Å).
متن کامل1-Methyl-1H-benzimidazole-2(3H)-thione
The title compound, C(8)H(8)N(2)S, was prepared by the condensation of N-methyl-1,2-phenyl-enediamine and carbon disulfide. The crystal structure is stabilized by a C-H⋯π inter-action between a benzene H atom and the benzene ring of a neighbouring mol-ecule, and by inter-molecular N-H⋯S inter-actions.
