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 کاملEthyl 4-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate
In the title compound, C(18)H(19)ClN(4)O(3), the dihydro-pyrimidin-one ring adopts a flattened boat conformation. The dihedral angle between the phenyl and pyrazole rings is 43.39 (6)°. An intra-molecular C-H⋯O contact generates an S(8) ring motif that stabilizes the mol-ecular conformation and precludes the carbonyl O atom of the ester group from forming inter-molecular inter-actions. Mol-ecul...

have been prepared and applied for the separation of the platinum-group metals, such as Pt, Pd, Ir and Rh, or tervalent lanthanides via solvent extraction.1–4 They are able to extract most metal ions at a lower pH than a related compound, βdiketones. We tried to prepare a novel derivative with an ethoxy group as an electron-releasing substituent, 1-phenyl-3methyl-4-ethoxyacetyl-5-pyrazolone, to...
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 کاملEthyl 6-chloro-2-methyl-4-phenylquinoline-3-carboxylate
In the title compound, C(19)H(16)ClNO(2), the quinoline ring system is planar (r.m.s. deviation = 0.008 Å). The phenyl group and the -CO(2) fragment of the ester unit form dihedral angles of 60.0 (1) and 60.5 (1)°, respectively, with the quinoline ring system.
