4-Methyl-2-n-propyl-1H-benzimidazole-6-carboxylic acid
In the title compound, C(12)H(14)N(2)O(2), the benzene ring and imidazole ring are almost coplanar, making a dihedral angle of 2.47 (14)°. Inter-molecular O-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds stabilize the crystal structure.

The asymmetric unit of the title compound, C(17)H(11)Cl(3)N(2)O(2), contains two independent mol-ecules; the pyrazole rings are oriented with respect to the chloro-phenyl and dichloro-phenyl rings at dihedral angles of 43.00 (3) and 65.06 (4)°, respectively, in one mol-ecule, and 51.17 (3) and 69.99 (3)°, respectively, in the other. Pairs of inter-molecular O-H⋯O hydrogen bonds link the mol-ecu...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(12)H(12)N(2)O(3)S. With the exception of the methyl-ene groups, a mean plane fitted through all non-H atoms of each mol-ecule has an r.m.s. deviation of 0.035 Å for one mol-ecule and 0.120 Å for the second. In one of the independent mol-ecules, the methyl-ene groups was refined using a disorder model with an oc...
متن کامل5-Methyl-1-phenyl-1H-1,2,3-triazole-4-carboxylic acid
The title compound, C(10)H(9)N(3)O(2), was synthesized from azido-benzene and ethyl acetyl-acetate. A pair of hydrogen bonds [2.617 (2) Å] inter-connects a pair of the carboxyl groups, forming an R(2) (2)(8) inversion dimer, a frequent motif in carboxylic acids. In the title structure, the bonding H atom in the aforementioned O-H⋯O hydrogen bond is significantly shifted towards the acceptor O a...
