4-(Dimethylamino)phenyl phenyl ketone

4-(Dimethyl­amino)phenyl phenyl ketone

In the crystal structure of the title compound, C(15)H(15)NO, the two benzene rings are twisted from each other by a dihedral angle of 47.97 (4)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions, and π-π inter-actions with a centroid-centroid distance of 3.8493 (5) Å are observed.

Bis[4-(4-amino­phenyl­sulfanyl)phenyl] ketone

The mol-ecule of the title compound, C(25)H(20)N(2)OS(2), has imposed twofold rotation symmetry. The dihedral angle formed by the two crystallographically independent phenyl rings is 79.23 (7)°. In the crystal packing, the mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, forming chains running parallel to [102].

Dichloridobis(phenyl 2-pyridyl ketone oxime)nickel(II) acetone solvate

The Ni atom in the title compound, [NiCl(2)(C(12)H(10)N(2)O)(2)]·C(3)H(6)O, adopts a distorted octa-hedral geometry, being ligated by four N atoms from two different phenyl 2-pyridyl ketone oxime ligands and two Cl atoms. In the crystal structure, inter-molecular O-H⋯Cl hydrogen bonds link the mol-ecules into a chain structure along [010]. There is a π-π contact between the pyridine rings [cent...

Crystal 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...
