2-(3,4-Dichloro­phen­yl)-N-(1,3-thia­zol-2-yl)acetamide

In the title compound, C₁₁H₈Cl₂N₂OS, the mean plane of the dichloro­phenyl ring is twisted by 61.8 (1)° from that of the thia­zole ring. In the crystal, mol­ecules are linked via pairs of N—H...N hydrogen bonds with an R₂²(8) graph-set motif, forming inversion dimers which stack along the a-axis direction.

2-(2,4-Di­chloro­phen­yl)-N-(1,3-thia­zol-2-yl)acetamide

In the title compound, C₁₁H₈Cl₂N₂OS, the mean plane of the di­chloro­phenyl ring is twisted by 72.4 (1)° from that of the thia­zole ring. In the crystal, mol­ecules are linked via pairs of N—H...N hydrogen bonds with an R₂²(8) graph-set motif and weak C—H...O inter­actions, forming inversion dimers which stack along the c-axis direction.

Methyl 2-{2-[(2-methyl­phen­oxy)meth­yl]phen­yl}-2-oxoacetate

In the title compound, C₁₇H₁₆O₄, the dihedral angle between the benzene rings is 4.4 (2)°. In the crystal, weak C—H...O hydrogen bonds connect mol­ecules along [001].

4-Hy­droxy-N-methyl­benzamide

Three independent mol­ecules comprise the asymmetric unit of the title compound, C₈H₉NO₂, in which the dihedral angles between the amide group and the benzene ring are 3.0 (2), 4.0 (3) and 3.3 (9)°. In the crystal, O—H...O hydrogen bonds and weak C—H...N inter­actions are observed, forming infinite chains along [101].

(2E)-1-(4-Chloro­phen­yl)-3-(4-nitro­phen­yl)prop-2-en-1-one

In the title compound, C₁₅H₁₀ClNO₃, a substituted chalcone, the dihedral angle between the benzene rings is 5.1 (7)°. The nitro group makes a dihedral angle of 12.5 (3)° with the benzene ring to which it is attached. In the crystal, weak C—H...O inter­actions link the mol­ecules into a one-dimensional array along [010]. The crystal studied was an inversion twin, with a refined ratio for the twin components of 0.6060 (9):0.3939 (1).
