Crystal structure of (4E)-4-(8-methoxy-2H-chromen-2-ylidene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
In the title compound, C20H16N2O3, the phenyl substituent attached to the pyrazole ring makes a dihedral angle of 4.87 (7)° with the rest of the mol-ecule. In the crystal, mol-ecules are connected into inversion dimers of the R 2 (2)(14) type by pairs of C-H⋯O inter-actions. π-π inter-actions exist between the benzene and pyrazole rings at a distance of 3.701 (1) Å. Similarly, π-π inter-actions...
متن کاملCrystal structure of (4R,5S)-4-methyl-3-methylsulfinyl-5-phenyl-1,3-oxazolidin-2-one
The absolute structure of the chiral asymmetric indole precursor title compound, C11H13NO3S, was confirmed by refinement of the Flack and Hooft parameters and is that expected based on the starting materials for the synthesis. The phenyl group subtends a dihedral angle of 56.40 (5)° with the mean plane of the oxazolidinone ring, which adopts an envelope conformation, with the C atom bearing the...
متن کاملCrystal structure of 5-(5-chloro-2-hydroxybenzoyl)-2-(2-methyl-1H-indol-3-yl)nicotinonitrile
In the title compound, C22H14ClN3O2, the indole unit is essentially coplanar, with a maximum deviation of 0.035 Å for the C atom bearing the methyl group. The central pyridine ring is inclined to the indole ring system by 43.7 (1)°. The dihedral angle between the phenyl ring and the indole ring system is 15.7 (2)°, while that between the phenyl ring and the central pyridine ring is 46.3 (1)°. T...
متن کاملCrystal structure of fac-[2-(4-methyl-5-phenylpyridin-2-yl)phenyl-κ2 C 1,N]bis[2-(pyridin-2-yl)phenyl-κ2 C 1,N]iridium(III)
In the title compound, [Ir(C11H8N)2(C18H14N)], the IrIII ion adopts a distorted octa-hedral coordination environment defined by three C,N-chelating ligands, one stemming from a 2-(4-phenyl-5-methyl-pyridin-2-yl)phenyl ligand and two from 2-(pyridin-2-yl)phenyl ligands, arranged in a facial manner. The IrIII ion lies almost in the equatorial plane [deviation = 0.0069 (15) Å]. In the crystal, int...
متن کاملCrystal structure of methyl endo-8-cyano-exo-8-methyl-3-oxo-2-oxabicyclo[2.2.2]oct-5-ene-6-carboxylate.
A photochemical cycloaddition reaction of methyl 2-pyrone-5-carboxylate with methacrylonitrile mainly gave a [4 + 2] cycloadduct, assigned as methyl endo-8-cyano-exo-8-methyl-3-oxo-2-oxabicyclo[2.2.2]oct-5-ene-6-carboxylate, whose structure was determined by an X-ray diffraction study. The formation of the cycloadduct was reasonably explained by considering a biradical intermediate having a les...
