The whole mol-ecule of the title compound, C14H14N4, is generated by twofold rotation symmetry. The twofold axis bis-ects the central -CH2-CH2- bond and the planes of the pyridine rings are inclined to one another by 65.60 (7)°. In the crystal, there are no significant inter-molecular inter-actions present.
Crystal structures of two N-(ar-yl)aryl-sulfonamides, namely, 4-meth-oxy-N-(4-methyl-phen-yl)benzene-sulfonamide, C14H15NO3S, (I), and N-(4-fluoro-phen-yl)-4-meth-oxy-benzene-sulfonamide, C13H12FNO3S, (II), were determined and analyzed. In (I), the benzene-sulfonamide ring is disordered over two orientations, in a 0.516 (7):0.484 (7) ratio, which are(More)
In the title salt, C14H20NO(+)·Cl(-), the piperidine ring adopts a chair conformation. In the crystal, the cations and anions are linked by classical N-H⋯Cl hydrogen bond and weak C-H⋯Cl and C-H⋯O hydrogen bonds; the C-H⋯O hydrogen bonds exhibit R 2 (2)(14) ring motifs while the C-H⋯Cl hydrogen bonds link the mol-ecules into chains along the a-axis(More)
In the title compounds, C14H9F4NO, (I), C14H9BrF3NO, (II), and C14H9F3INO, (III), the two benzene rings are inclined to one another by 43.94 (8)° in mol-ecule A and 55.66 (7)° in mol-ecule B of compound (I), which crystallizes with two independent mol-ecules in the asymmetric unit, but by only 10.40 (12)° in compound (II) and 12.5 (2)° in compound (III).

In the title compound, C28H18N2O5, the dihedral angle between the terminal benzoate rings is 20.67 (12)°. The central oxadiazole ring is almost coplanar with its two benzene ring substituents, making dihedral angles of 4.80 (16) and 5.82 (16)°. In the crystal, pairs of C-H⋯O hydrogen bonds form inversion dimers with R 2 (2)(40) ring motifs. The structure(More)
In the title compound, C14H17FN2O, the 1,2,3,4-tetra-hydro-pyridine ring of the quinoline moiety adopts a half-chair conformation, while the pyrrolidine ring has an envelope conformation with the central methyl-ene C atom as the flap. The pyrrolidine ring lies in the equatorial plane and its mean plane is normal to the mean plane of the quinoline ring(More)
In the title compound, C13H14N2O2, the C5 ring has an envelope conformation with the C atom adjacent to the quaternary C being the flap. The five atoms comprising the imidazolidine-2,4-dione ring are almost planar (r.m.s. deviation = 0.004 Å). The dihedral angle between the five-membered rings is 89.66 (10)°. In the crystal, inversion-related mol-ecules are(More)
The structural modification and molecular docking-based screening approaches on thiazole-based isoindolinediones were imposed to find the novel 2-(4-phenylthiazol-2-yl) isoindoline-1,3-dione derivatives. The best fit compounds (6a-n) were synthesized and evaluated their antiproliferative activities on the prostate cancer cell lines (PC-3 & LNCaP). Among(More)
In the title compound, C14H13NO4S, the dihedral angle between the aromatic rings is 69.81 (1)°; the dihedral angle between the planes defined by the S-N-C=O segment of the central chain and the sulfonyl benzene ring is 74.91 (1)°. In the crystal, the mol-ecules are linked by weak N-H⋯O hydrogen bonds into C(4) chains running along [100]. The mol-ecules in(More)
