Crystal Structure of Schiff base Compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol
Single crystals of Schiff base compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol (1) were grown by the slow evaporation technique at room temperature. The crystal structure of the title compound was determined by single crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21, with two symmetry independent molecules. Intramolecular O-H···N hydr...
متن کاملCrystal structure of 4-chloro-2-iodoaniline
In the crystal structure of the title compound, C6H5ClIN, the amino group engages in N-H⋯N hydrogen bonding, creating [100] chains. A Cl⋯I contact is observed [3.7850 (16) Å]. The parallel planes of neigbouring mol-ecules reveal highly offset π-stacking characterized by a centroid-centroid distance of 4.154 (1), a centroid-to-plane distance of 3.553 (3) and ring-offset slippage of 2.151 (6) Å.
متن کاملCrystal structure of 2-(4-chloro-3-fluorophenyl)-1H-benzimidazole
In the title compound, C13H8ClFN2, the dihedral angle between the plane of the benzimidazole ring system (r.m.s. deviation = 0.022 Å) and the benzene ring is 26.90 (8)°. The F atom at the meta position of the benzene ring is disordered over two sites in a 0.843 (4):0.157 (4) ratio. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, forming infinite C(4) chains propagating along [010...
متن کاملCrystal structure of 4,5-bis(4-dimethylaminophenyl)-2-(4-nitrophenyl)imidazole.
A nonlinear optical chromophore, 4,5-bis(4-dimethylaminophenyl)-2-(4-nitrophenyl)imidazole, was investigated by X-ray crystallography. The study focused on coplanarity among several aromatic rings, including phenyls and imidazole. Two phenyl rings with NMe2 groups are twisted by 46.39(3) degrees from each other. However, they are twisted by 23.05(5) degrees and 46.84(3) degrees from the imidazo...
متن کاملSynthesis and Bioevaluation of 4-[(2/4-chloro-/2, 3-dichloro-/2/4-bromo-/2, 4-dinitro-/4-nitrophenyl) Anilinomethyl]-6-t-butyl-2H-1-benzopyran-2-ones
Synthesis of 4-[(2/4-chloro-/2,3-dichloro-/2/4-bromo-/2,4-dinitro-/4-nitrophenyl) anilinemethyl]6-t-butyl-2H-1-benzopyran-2-ones have been carried out. Synthesized compounds were characterized by 1HNMR, IR and other physical and analytical data. All of the synthesized compounds were evaluated for their antifungal activity against Aspergillus awamori and Sclerotium rolfsii and antibacterial acti...
