The title compound, CHNO, was obtained the reaction of -allyl--phenyl-acryl-amide with 3-iodo-cyclo-hex-2-en-1-one using PdCl(PPh) as a catalyst. The compound crystallizes in the monoclinic space group 2/. The fused-ring system is not planar and the five- and six-membered rings are -fused. The mol-ecular geometry is partially stabilized by an intra-molecular C-H⋯O hydrogen bond, forming an (6) ring motif. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯π inter-actions into a three-dimensional network. To further analyse the inter-molecular inter-actions, a Hirshfeld surface analysis was performed. The results indicate that the most important contributions to the overall surface are from H⋯H (65.5%), O⋯H/H⋯O (17.5%) and C⋯H/H⋯C (14.3%) inter-actions.

Two octa-coordinated lanthanum (III) complexes of deprotonated azaphosphor β-diketon and diimine ligands, [LnLQ] (L = [ClCHC(O)NP(O)(NCH)], Q = Phen (C1) and Bipy (C2)), were synthesized and characterized by elemental analysis, IR, and NMR spectra. X-ray crystallography revealed a distorted tetragonal antiprism LaO6N2 coordination geometry around the lanthanum atom in both compounds. Nano-sized complexes (Ć1 and Ć2) were synthesized via a sonochemical process and analyzed using SEM and XRPD.

Context: Schiff bases, which have intriguing properties in many areas, have been studied extensively in recent years due to their structural properties and biological activities. In this research, a novel water-soluble Schiff base complex, Catena-((μ-(E)-2-((4-methoxy-2-oxidobenzylidene) ammonio) ethane-1-sulfonato potassium, CHKNOS (CMOAESP), was synthesized by a one-step condensation reaction of 2-hydroxy-4-methoxy benzaldehyde and taurine with the yield of 65%, 0.333 g.

8-Hydroxyquinoline and imidazole, two important N-heteroaromatic systems, have a strong affinity towards various anions their acidic OH or NH protons. Three receptor ligands, 5-(1-benzo[]imidazol-2-yl)quinolin-8-ol (1), 5-(benzo[]thiazol-2-yl)quinolin-8-ol (2), and 4-(1-benzo[]imidazol-2-yl)benzene-1,3-diol (3), were synthesized, and their fluoride (F) ion binding properties were investigated. These ligands could selectively bind F ions, and their respective F complexes, namely, 1-TBAF, 2-TBAF, and 3-TBAF (TBAF = tetrabutylammonium fluoride), were characterized using single crystal X-ray analysis, NMR, UV-vis, Hirshfeld surface (HS) analysis and computational studies.

In search of novel antidiabetic agents, we synthesized a new series of chalcones with benzimidazole scaffolds by an efficient 'one-pot' nitro reductive cyclization method and evaluated their α-glucosidase and α-amylase inhibition studies. The 'one-pot' nitro reductive cyclization method offered a simple route for the preparation of benzimidazoles with excellent yield and higher purity compared to the other conventional acid- or base-catalyzed cyclization methods. H, C NMR, IR, and mass spectrum data were used to characterize the compounds.
