Reactions of the Schiff base ligand OH-C6H4-CH[dbnd]NC(CH2OH)3 (H4L) with copper(II) salts in various reaction media afforded complexes [Cu4(H2L)4]·MeOH (1·MeOH), [Cu2(O2CMe)2(H3L)2] (2), [Cu4(H2L)4(H2O)2]·1.5dmf (3·1.5dmf), [Cu4(H2L)4(H2O)]·MeOH (4·MeOH) and [Cu4(H2L)4]2·2H2O·7MeOH (5·2H2O·7MeOH). Compounds 1, 3 and 4 consist of neutral tetranuclear entities in which the CuII ions are coordinated by the tridentate Schiff base ligands, forming a tetranuclear Cu4O4 cubane-like configuration. Compound 5 contains similar cubane-like tetranuclear entities which are further linked through the hydroxyl groups of the ligands thus forming dimers of cubanes. Compound 2 contains a neutral dinuclear entity in which the CuII ions are bridged through the Schiff base and the acetate ligands, comprising distorted Cu2O2 core. The Schiff base ligand adopts five different coordination modes and two deprotonation states in the structures of 1?5 acting simultaneously as chelating and bridging agent between the metal ions. The lattice structures of 1?5 exhibit interesting 3D networks based on hydrogen bonded metal clusters and they are studied with Hirshfeld Surface analysis methods.

Flavonoids are a class of natural products, found in a wide range of vascular plants and dietary components. Their low toxicity and extensive biological activities, including anti-cancer and anti-bacterial, have made them attractive candidates to serve as therapeutic agents for many diseases. Herein, we disclose a highly efficient synthetic method of CuI-catalyzed cascade oxa-Michael-oxidation, using chalcones as substrates, mediated by the ionic liquid [bmim][NTf2] at a low temperature. This efficient synthetic method has demonstrated high synthetic utility and can afford flavones in good to high yields (up to 98%).

The magnetic properties of chalcogenide spinel CuCr2Se4 nanocrystals have been studied as a function of crystallite size (15-30 nm). A solution-based method is used for the facile synthesis of the nanocrystals with good size control. They have close to cubic morphology with a narrow size distribution and exhibit superparamagnetic behavior at room temperature. The Curie temperature and saturation magnetization of the nanocrystals are lower as compared with the bulk and decrease with decreasing nanocrystal size. A similar trend is observed in the paramagnetic state for the Curie-Weiss temperature and effective magnetic moment. The low temperature magnetization behavior can be qualitatively explained by spin glass dynamics.

The kinetics and mechanism of copper film growth from the reactions of bis(acetylacetonato)copper(II), bis(hexafluoroacetylacetonato)copper(II), and (vinyltrimethylsilane)(hexafluoroacetylacetonato)copper(I) (Cu(hfac)(vtms)) with copper single crystal surfaces were investigated. Experiments were performed using vibrational spectroscopy (reflection infrared and high-resolution electron energy loss spectroscopies) as well as mass spectrometry (temperature-programmed desorption and integrated desorption mass spectrometries). Both ligand desorption and dissociation were observed upon pyrolysis of these molecules under ultra-high-vacuum conditions. We demonstrate that adsorbed beta-diketonate ligands decompose in a stepwise fashion at temperatures above ?375 K to yield adsorbed CF3 and ketenylidene (?C-C?O) intermediates. These further decompose above ?500 K to leave surface carbon, a major contaminant in copper films grown from CuII beta-diketonates. Clean films can be grown from the pyrolysis of Cu(hfac)(vtms) at pressures above 10-5 Torr, however. The implications of our results relative to the mechanism of copper film growth at elevated pressures are also discussed.
