Molecular geometry from X-ray experiment of the title compound in the ground state have been compared using the Hartree-Fock (HF) and density functional method (B3LYP)(More)
The title compound, C(16)H(17)NO, is a Schiff base which adopts the phenol-imine tautomeric form in the solid state. The mol-ecule is almost planar, with a dihedral angle of 4.61 (4)° between the aromatic rings. The molecular structure is stabilized by an intramolecular O-H⋯N hydrogen bond which generates a six membered ring.
The title Schiff base, C(19)H(24)N(2)O(3), exists in the crystal structure in the phenol-imine tautomeric form with an intra-molecular O-H⋯N hydrogen bond. The planes of the aromatic rings form a dihedral angle of 36.8 (8)°. The crystal packing is characterized by C-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.478 (4)Å].
In the mol-ecule of the title compound, C(23)H(17)N(3)O(2), the methoxy-phenyl ring is oriented at dihedral angles of 13.34 (12) and 88.83 (12)° with respect to the methyl-phenyl and phthalonitrile rings, respectively; the dihedral angle between methyl-phenyl and phthalonitrile rings is 89.67 (10)°. In the crystal structure, weak inter-molecular C-H⋯N(More)
The title Schiff base, C(17)H(19)IN(2)O, is not planar, displaying a dihedral angle of 34.9 (2)° between the two aromatic rings. The mol-ecular conformation allows the formation of a strong intra-molecular O-H⋯N hydrogen bond with graph-set motif S(6) between the hy-droxy group and the imine N atom.
The mol-ecule of the title compound, C(23)H(17)NO(2), a Schiff base derived from 2-hydr-oxy-1-naphthaldehyde, crystallizes in the keto-amine tautomeric form. The dihedral angle between the aniline and hydroxy-benzene rings is 77.41 (17)°, whereas the planes of the naphthaldehyde and fused aniline benzene rings are nearly coplanar, making a dihedral angle of(More)
The title molecule, (E)-3-chloro-N-((5-nitrothiophen-2-yl)methylene)aniline, (C(11)H(7)ClN(2)O(2)S), was synthesized and characterized by IR and single-crystal X-ray structure determination. The compound crystallizes in the monoclinic space group P2(1)/c. In addition, the molecular geometry, vibrational frequencies and frontier molecular orbitals analysis(More)
The title compound, C(13)H(13)ClN(4)O(2), contains both a phenyl and a triazole ring, both of which are approximately coplanar with the entire molecule. The triazole ring has substituents at the 1-, 2- and 4-positions. Intramolecular C-H.O and C-H.N interactions, together with intermolecular C-H.O and C-H.pi interactions, help to stabilize the structure.
