The title compound was synthesized from reaction of 1-(benzofuran-2-yl)-3-(4-fluorophenyl)prop-2-en-1-one with thiosemicarbazide in ethanolic sodium hydroxide under reflux for 12 h. The solid obtained on cooling was recrystallized from dimethylformamide to give colorless crystals of the title compound (Mp. 260–262 °C) [6].
Cell refinement and data reduction were carried out by Bruker SAINT [4]. The hydrogen atoms were placed on calculated positions with the help of the SHELX program (AFIX option 13, 23 and 43) [5]. The atoms O1/O7A und C7,H7/C1A,H1A are disordered and were split in the refinement in two parts with occupancy factors of 0.827(7) (O1, C7, H7) and 0.173(7) (O7A, C1A, H1A). The figure shows only one part for clarity.
Pyrazolin-1-carbothioamide derivatives show some interesting biological activities such as antibacterial [1], antifungal [2] and anticancer properties [3].
In the title compound, the asymmetric unit contains one independent molecule. The central pyrazol ring (N1/N2/C9—C11) makes the dihedral angles of 15.28(2)° and 83.11(3)° with the benzofuran ring (O1/C1—C8) and the fluorophenyl ring (C12—C17), respectively. Consequently, the fluorophenyl ring is nearly perpendicular to the plane of whole molecule (cf. Figure). The structure shows at least two hydrogen bonds between N3—H2N3⋯F1i and N3—H1N3⋯S1ii with symmetry code: (i) x, y, z−1; (ii) x, −y+1/2, z−1/2.
