PbS:Cu nanocrystalline films were prepared by chemical bath at temperature of 80 degrees C and deposited on glass substrates. Different Cu-doping levels obtained changing the volume Cu-reagent-solution into PbS growing solution. X-ray diffraction (XRD) optical absorption (OA) measurements carried out to characterize semiconductor. The morphological changes layers analyzed using an atomic force microscopy. Diffraction spectra displayed peaks 2 theta = (26.00, 30.07, 43.10, 51.00 53.48),...
Herein, we report the morphological, optical, and structural modifications induced by change of different functional groups in para-position benzene ring a series chiral imines. These organic compounds were examined using scanning electron microscopy (SEM), optical absorption, X-ray diffraction, photoluminescence (PL) techniques. SEM images showed drastic morphological changes, absorbance results significant changes bands located ∼200–400 nm range, associated with π → π*, δ δ*, n π*...
Abstract Optically pure α‐diimines quantitatively obtained in solvent‐free conditions starting from 2,3‐butanedione and ( S )‐(−)‐1‐phenylethylamine )‐(−)‐1‐(4‐methylphenyl)ethylamine, respectively, yielded the new chiral mono‐Pd complexes 2a–b, which have been partly characterized by IR, 1 H‐ 13 C‐NMR spectroscopies along with MS‐FAB + spectrometry. The crystal molecular structure for palladacycle 2a has fully confirmed single‐crystal X‐ray studies. Studies vitro of 2a–b displayed growth...
The crystal structures of three complexes [HgCl2 L] were determined, namely, (S)-(+)-di-chlorido-[1-phenyl-N-(pyridin-2-yl-methyl-idene)ethyl-amine-κ(2) N,N']mercury(II), [HgCl2(C14H14N2)], (S)-(+)-di-chlorido-[1-(4-methyl-phen-yl)-N-(pyridin-2-yl-methyl-idene)ethyl-amine-κ(2) [HgCl2(C15H16N2)], and (1S,2S,3S,5R)-(+)-di-chlorido-[N-(pyridin-2-yl-methyl-idene)isopino-camph-eyl-amine-κ(2) [HgCl2(C16H22N2)]. consist a bidentate chiral imine ligand coordinating to HgCl2 crystallize with four...
The ( S )-(+)-1-(4-bromophenyl)- N -[(4-methoxyphenyl)methylidene]ethylamine ligand, C 16 H BrNO, (I), was synthesized through the reaction of 4-methoxyanisaldehyde with )-(−)-1-(4-bromophenyl)ethylamine. It crystallizes in orthorhombic space group P 2 1 belonging to Sohncke group, featuring a single molecule asymmetric unit. refinement converged successfully, achieving an R factor 0.0508.

Optically pure α-ketoimines were obtained under solvent-free conditions starting from 2,2′-pyridil and (S)-(−)-1-phenylethylamine (S)-(−)-1-(4-methylphenyl)ethylamine, respectively. These new chiral ketoimines then complexed with palladium yielding optically mono-Pd complexes 3A–B. The compounds have been characterized by IR, 1H NMR, 13C NMR spectroscopies along MS-FAB+ spectrometry. crystal molecular structure of 3A has fully confirmed single-crystal X-ray studies. In vitro studies 3A–B...

The structure of the title solvate, C(9)H(6)O(6)·C(2)H(6)OS, was determined 30 years ago [Herbstein, Kapon & Wasserman (1978 ▶). Acta Cryst. B34, 1613-1617], with data collected at room temperature, and refined in space group P2(1). present redetermination, based on high-resolution diffraction data, shows that actual is more likely to be P2(1)/m. crystal contains layers trimesic acid molecules lying mirror planes. A plane also passes through S O atoms solvent molecule. each layer are...
A series of thio-phenes substituted in positions 2 and 5 by imine groups have been synthesized using a solvent-free approach, their crystal structures determined.
