5-(4-Fluorophenyl)-2-[2-(5-phenyl-1,3-oxazol-2-yl)phenyl]-1,3-oxazole
In the title compound, C(24)H(15)FN(2)O(2), the dihedral angles between the central benzene ring and the oxazole rings are 10.7 (6) and 64.1 (5)°. The dihedral angles between the oxazole rings and their pendant rings are 2.0 (3) and 24.3 (2)°. The F atoms are disordered over two sites with occupancies of 0.627 (3) and 0.373 (3) in the phenyl-ene-oxazol-yl-phenyl and in oxazol-yl-phenyl fragment...
متن کامل5-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 ...
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...
متن کامل4-(5-tert-Butyl-1,3-dithian-2-yl)-5-chloro-2-phenyl-1,3-oxazole
In the title mol-ecule, C(17)H(20)ClNOS(2), the phenyl and oxazole rings are nearly coplanar with an average deviation of 0.022 Å from the mean plane (M). The 1,3-dithiane ring adopts a chair conformation and is twisted in such a way that the C-C(Bu) fragment lies in M (deviations are 0.031 and 0.010 Å, respectively, for the two C atoms).
متن کامل5-Methylisoxazole-4-carboxylic acid
In the title compound, C(5)H(5)NO(3), the mol-ecule lies on a crystallographic mirror plane with one half-mol-ecule in the asymmetric unit. An intramolecular C-H⋯O inter-action is present. In the crystal, strong inter-molecular O-H⋯N hydrogen bonds result in the formation of a linear chain structure along [100], and there are also weak C-H⋯O hydrogen bonds between the chains which help to stabi...
