Methyl 3-carboxy-5-nitrobenzoate
The structure of the title compound, C(9)H(7)NO(6), is essentially planar [maximum deviation 0.284 (2)Å] except for the methyl H atoms. The crystal structure is stabilized by asymmetric O-H⋯O hydrogen bonds linking the hydrogen carboxyl-ates into pairs around the inversion centres. There is also π-π stacking of the benzene rings [centroid-centroid distance 3.6912 (12) Å].

The title compound, C(29)H(19)F(6)NOS(2), is a new unsymmetrical photochromic diarylethene derivative with different meta-phenyl substituents. The distance between the two reactive (i.e. can be irradiated to form a new chemical bond) C atoms is 3.501 (4) Å; the dihedral angles between the mean plane of the main central cyclo-pentene ring and the thio-phene rings are 47.7 (5) and 45.1 (2)°, and ...
متن کامل2-(4-Chlorophenyl)-4-[1-(4-chlorophenyl)-3-methyl-1H-pyrazol-5-yl]-5-methyl-1H-pyrazol-3(2H)-one
The title compound, C(20)H(16)Cl(2)N(4)O, has two mol-ecules in the asymmetric unit. The two five-membered rings form a dihedral angle of 54.2 (3)° in one mol-ecule and 56.8 (3)° in the other independent mol-ecule. The amino group of the dihydro-pyrazolone unit of one mol-ecule acts as a hydrogen-bond donor to the carbonyl group of the dihydro-pyrazolone system of the other mol-ecule. The resul...

Methyl 2,5-dihydroxy-4-(31-methyl-21-butenyl)benzoate (1) was isolated from the root of Erythrina subumbrans. The chemical structure of 1 has been elucidated based on spectroscopy UV-Vis, HRESIMS, 1D and 2D NMR analysis.
متن کامل5-Chloro-2-methyl-3-(4-methylphenylsulfonyl)-1-benzofuran
The title compound, C16H13ClO3S, crystallized with two independent mol-ecules in the asymmetric unit. The 4-methyl-phenyl rings make dihedral angles of 75.15 (4)° and 72.18 (4)° with the planes of the benzo-furan ring systems in the two mol-ecules. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions, forming a three-dimensional network.
