4-Chloro-2-[1-(4-ethyl­phen­yl)-4,5-di­phenyl-1H-imidazol-2-yl]phenol

In the title compound, the 5-chloro­phenol ring and the imidazole ring are nearly coplanar, with a dihedral angle of 15.76 (9)°. The ethyl­phenyl ring and the two phenyl rings subtend at angles of 71.09 (7), 43.95 (5) and 36.53 (9)°, respectively, with the imidazole plane.

N′-(2-Hy­droxy-3-meth­oxy­benzyl­idene)pyrazine-2-carbohydrazide monohydrate

In the title hydrated Schiff base, the dihedral angle between the aromatic rings is 5.06 (11)° and an intra­molecular O—H⋯N hydrogen bond closes an S(6) ring. In the crystal, O_w—H⋯O and O_w—H⋯N (w = water) hydrogen bonds link the components into centrosymmetric tetra­mers (two Schiff bases and two water mol­ecules). Longer N—H⋯O hydrogen bonds link the tetra­mers into [010] chains.

The crystal structure of a biologically important pharmacophore containing 1,4-di­hydro­pyridine is reported.

(E)-1-(4-Fluoro-2-hy­droxy­phen­yl)-3-(2,3,4-tri­meth­oxy­phen­yl)prop-2-en-1-one

The crystal structure of a biologically important pharmacophore containing chalcone is reported.

[4-(4-Meth­oxy­phen­yl)-8-oxo-3-(phenyl­selan­yl)spiro­[4.5]deca-3,6,9-trien-2-yl]methyl­cyanamide

The title compound, C₂₅H₂₂N₂O₂Se, crystallizes in the space group P2₁/c with one mol­ecule in the asymmetric unit. The compound was synthesized by addition of phenyl­selenyl bromide to a cyanamide.

Benzene-1,2-diaminium bis­(4-methyl­benzene-1-sulfonate)

In the structure of the title compound, which consists of a unique benzene-1,2-diaminium dication charge-balanced by a pair of crystallographically independent 4-methyl­benzene-1-sulfonate anions, the cations and anions are inter­linked by several N—H⋯O hydrogen bonds.

2-[(5-Chloro­pyridin-2-yl­imino)­meth­yl]phenol

In the crystal, C—H⋯O and C—H⋯N hydrogen bonds connect the mol­ecules into [001] chains.

3-(4-Iodo­phen­yl)-2,3-di­hydro-1H-benzo[f]chromen-1-one

In the crystal of the title flavone derivative, O⋯I halogen bonding and T–shaped π–stacking combine to generate a herringbone packing motif.
