Source of material

A mixture of thiophene-2-carbohydrazide (142.2 mg, 1 mmol) and 1-(5-chloro-2-hydroxyphenyl)ethanone (170.6 mg, 1 mmol) was dissolved in 25 mL anhydrous ethanol containing a catalytic amount of glacial acetic acid. The reaction mixture was stirred under reflux for 3 h, then cooled to room temperature and filtered, and then left at room temperature. After six days, yellow block crystals were obtained.

Experimental details

All hydrogen atoms were positioned geometrically (C–H = 0.93–0.96 Å, O–H = 0.82 Å, N–H = 0.86 Å) and refined using a riding model approximation. The U iso values were constrained to be 1.5 U eq of the carrier atom for oxygen atom and methyl groups and 1.2 U eq for the remaining H atoms.

Comment

Thiophene hydrazone schiff bases are attracting more and more attention due to their biological activities and wide applications in coordination chemistry [3], [4], [5], [6], [7], [8], [9], [10].

The asymmetric unit of the title compound consists of one molecule of the organic target compound (see the figure). The title compound shows an E configuration around the C6=N2 bond. In the crystal structure, the short distance d(C6–N2) = 1.296(7) Å shows a typical C=N double bond. The angle of C6=N2–N1 is 118.4(5)°. In general the bond lengths and angles are as expected [11, 12]. The thiophene and the 5-chloro-2-hydroxyphenyl ring are almost parallel, with the dihedral angle of 1.6°. In the crystal structure, the molecules are linked into chains along the b-axis by O–H⃛N and C–H⃛O hydrogen bonds. One intramolecular N–H⃛O hydrogen bond exists, which stabilizes the conformation of the title molecule (see the figure).
