5-Amino-1-phenyl-1H-pyrazole-4-carboxylic acid
In the mol-ecule of the title compound, C(10)H(9)N(3)O(2), the pyrazole ring is approximately coplanar with the amino and carboxyl groups. The phenyl group is twisted by 48.13 (3)° relative to this plane. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation of the mol-ecule. The mol-ecules are linked into two-dimensional sheets by two strong inter-molecular N-H⋯N and O-H⋯O ...

In the crystal structure of the title compound, C(17)H(15)FN(2)O, the mol-ecules form a three-dimensional network stabilized by π-π inter-actions between two imidazole rings related by a centre of symmetry. The distance between the centroids is 3.5488 (8) Å. The imidazole ring makes dihedral angles of 14.30 (7) and 33.39 (7)° with the 4-fluoro-phenyl ring and the phenyl ring, respectively.
متن کامل4-Phenyl-1H-imidazole-2(3H)-thione
In the asymmetric unit of the title compound, C(9)H(8)N(2)S, there are four symmetry-independent mol-ecules (Z' = 4). The geometrical features of these mol-ecules are quite similar: in the normal probability plots the R(2) correlation factors for bond lengths and angles are generally around 0.95. The twist angles between the imidazole and phenyl rings (which are planar within 3σ) range from 9.0...
متن کامل2-Phenyl-1H-imidazole
In the title compound, C(9)H(8)N(2), a mirror plane lies perpendicular to the phenyl and imidazole rings and passes through the bridging C-C bond, so that the imidazole ring is disordered over two sites about the mirror plane with the equal site occupancy; the asymmetric unit contains one half-mol-ecule. In the crystal, adjacent mol-ecules are linked via N-H⋯N hydrogen bonds.
متن کامل4-Phenyl-1H-imidazole (a low-temperature redetermination), 1-benzyl-1H-imidazole and 1-mesityl-1H-imidazole.
Low-temperature studies of the simple variously substituted imidazole types 4-phenyl-1H-imidazole, C9H8N2, 1-benzyl-1Himidazole, C10H10N2, and 1-mesityl-1H-imidazole, C12H14N2, extend comparisons between parent imidazole species and their derivatives, the pronounced double-bond localization opposite the substituted N atom common to simple neutral species being redistributed aromatically on prot...
