1.  Novel Antimicrobial Agents: Fluorinated 2-(3-(Benzofuran-2-yl) pyrazol-1-yl)thiazoles 
A new series of 2-pyrazolin-1-ylthiazoles 8a–d and 13–16 was synthesized by cyclization of N-thiocarboxamide-2-pyrazoline with different haloketones and 2,3-dichloroquinoxaline. The structures of the new compounds were confirmed by elemental analyses as well as NMR, IR, and mass spectral data. The newly synthesized compounds were evaluated for their antimicrobial activities, and also their minimum inhibitory concentration (MIC) against most of test organisms was performed. Amongst the tested ones, compound 8c displayed excellent antimicrobial activity.

2.  (2E)-1-[5-Methyl-1-(4-methyl­phen­yl)-1H-1,2,3-triazol-4-yl]-3-[4-(piperidin-1-yl)phen­yl]prop-2-en-1-one1  
Two independent mol­ecules comprise the asymmetric unit of the title compound, C24H26N4O. The major difference between them is found in the relative orientation of the triazole-bound p-tolyl group which have the opposite sense of twist [N—N—C—C torsion angles = 55.8 (3) and −49.8 (3)°]. The chalcone residue is almost coplanar with the triazole ring [N—C—C—O and C—C—C—C torsion angles = −178.9 (2) and −178.5 (2)°, respectively; cf. 177.9 (3) and 168.5 (3)°, respectively, in the second mol­ecule]. The conformation about each C=C double bond is E and in each case the triazole methyl group is syn to the carbonyl O atom. In the crystal, mol­ecules aggregate into layers parallel to (-113). The first independent mol­ecule self-associates into a layer via C—H⋯O and C—H⋯π inter­actions. By contrast, layers comprising the second independent mol­ecule do not feature specific inter­actions between mol­ecules. The global crystal packing comprises alternating layers.

3.  5-(4-Fluoro­phen­yl)-3-[5-methyl-1-(4-methyl­phen­yl)-1H-1,2,3-triazol-4-yl]-4,5-dihydro-1H-pyrazole-1-carbothio­amide 
In the title compound, C20H19FN6S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The dihedral angle between the least-squares plane through the pyrazole and triazole rings is 7.59 (9)°, and the triazole and attached benzene ring form a dihedral angle of 74.79 (9)°. The thio­urea group is coplanar with the pyrazole ring [N—N—C—S torsion angle = −179.93 (11)°], which enables the formation of an intra­molecular N—H⋯N hydrogen bond. In the crystal, inversion-related mol­ecules associate via N—H⋯S hydrogen bonds and eight-membered {⋯HNCS}2 synthons feature in the crystal packing. These synthons are connected into supra­molecular chains along the a axis via N—H⋯F hydrogen bonds, and the chains are consolidated into layers in the ab plane via C—H⋯S and C—H⋯F contacts.
