Crystal structure and Hirshfeld surface analysis of rac-2-[2-(4-chloro-phen-yl)-3,4-di-hydro-2H-1-benzo-pyran-4-yl-idene]hydrazine-1-carbo-thio-amide.

ABSTRACT: In the title compound, C16H14N3OSCl, a Schiff base derivative of a thio-semicarbazide with a flavanone, the 4-chlorophenyl ring is inclined to the benzene ring of the chromane ring system by 30.72?(12)°. The pyran ring has an envelope conformation with the methine C atom as the flap. The mean plane of the thio-urea unit is twisted with respect to the benzene ring of the chromanone ring system, subtending a dihedral angle of 19.78?(19)°. In the crystal, mol-ecules are linked by two pairs of N-H?S hydrogen bonds, forming inversion dimers enclosing R 2 2(8) ring motifs, which are linked to form ribbons propagating along the b-axis direction. The inter-molecular contacts in the crystal have been analysed using Hirshfeld surface analysis.
