In the title compound, [ZnCl2(C14H12N2)2], the Zn(II) atom exhibits a distorted tetra-hedral coordination geometry involving two chloride anions and two N-atom donors from 1-benzyl-1H-benzimidazole ligands. In both ligands, the benzyl and benzimidazole rings are nearly perpendicular [dihedral angles = 81.7 (2) and 81.5 (2)°]. The two benzimidazole systems(More)
Three new polyketides ((-)-1, (+)-1, and 2) were isolated from the EtOAc extract of the fungus Embellisia eureka, an endophyte of the Moroccan plant Cladanthus arabicus (Asteraceae). The structures of these new compounds were determined on the basis of one- and two-dimensional NMR spectroscopy as well as by high-resolution mass spectrometry. The absolute(More)
This study aimed at developing a biocomposite using polypropylene (PP) as the matrix and Argan nut shell (ANS) as reinforcement. Also, styrene-(ethylene-butene)-styrene triblock copolymer grafted with maleic anhydride (SEBS-g-MA) was used as a coupling agent. The samples were prepared by using extrusion compounding followed by injection molding to determine(More)
Three natural clay-based microstructures, namely layered montmorillonite (MMT), nanotubular halloysite (HNT) and micro-fibrillar sepiolite (SP) were used for the synthesis of hybrid chitosan-clay thin films and porous aerogel microspheres. At a first glance, a decrease in the viscosity of the three gel-forming solutions was noticed as a result of breaking(More)
The bonds in the five-membered ring of the title hydrated salt, C(14)H(17)N(2) (+)·Br(-)·2H(2)O, are delocalized. The cation lies on a special position of m site symmetry such that the mirror plane passes through the imidazol-yl-methyl bond and is perpendicular to the plane of the cation. The anion lies on another special position of 2 site symmetry. The(More)
The intimate interplay of chitosan (CS) and graphene oxide (GO) in aqueous acidic solution has been explored to design upon casting, nanostructured "brick-and-mortar" films (CS-GO-f) and by acidic-to-basic pH inversion, porous CO2-dried aerogel microspheres (CS-GO-m). Owing to the presence of oxygenated functional groups in GO, good-quality crack-free(More)
In the mol-ecule of the title compound, C7H9N5O·0.40H2O, the seven-membered heterocyclic ring exhibits a boat conformation, whereas the five-membered triazole ring is almost planar (r.m.s. deviation = 0.005 Å). In the crystal, centrosymmetric dimers are linked by pairs of C-H⋯O hydrogen bonds into dimers, which are further connected via O-H⋯N and C-H⋯N(More)
The aim of this work is to develop a new bio-composite based on polylactic acid (PLA) reinforced with argan nut shells (ANS). In this study, the effect of ANS chemical surface treatments on the morphological, mechanical, thermal, and rheological properties of PLA was investigated. In particular, a comparison between three chemical treatments (alkali,(More)
In the title compound, C(15)H(14)N(4), the phenyl and pyrazole rings are essentially coplanar, being twisted relative to each other by a dihedral of only 3.68 (11)°. The benzene ring makes a dihedral angle of 64.47 (11)° with the pyrazole ring. The crystal structure is stabilized by two inter-molecular N-H⋯N hydrogen-bonds, which build a two-dimensional(More)
The benzimidazole ring in the title compound, C16H17N3O2S, is almost planar, with the greatest deviation from the mean plane being 0.032 (1) Å. The fused-ring system makes dihedral angles of 19.91 (7) and 24.51 (8)° with the best plane through each of the thia-zol-4-yl and 1,3-dioxolan-4-yl rings, respectively; the latter exhibits an envelope conformation(More)
