An Efficient Nonlinear Optical, Magnetic Transition Metal Ion Nickel Doped L- Threonine Cadmium Acetate Monohydrate

The semi organic nonlinear optical single crystal of L- Threonine Cadmium acetate Monohydrate (LTCAM) doped Ni 2+ion is prepared by the technique slow evaporation solution growth. The prepared crystal was analysed by XRD, EDAX, UV-Vis- NIR, IR, TG/DTA, Photo Luminescence (PL), VSM and SHG measurements. The SXRD shows the crystal come under the monoclinic crystal system with P21 noncentrosymmetric space group. In the visible and near infrared region the crystal shows good optical response and it is a thermally stable compound. The band gap of the grown crystal was 5.02ev. The functional groups are confirmed by FTIR analysis. The luminescent behaviour of the doped crystal shows its ability as UV filters. The dopant turns its magnetic property in to semi paramagnetic nature.

Fabrication and characterization of supramolecular Cu-based metallogel thin-film based Schottky diode

In the present study, a stable supramolecular Cu (II)-metallogel has been synthesized via Copper (II) acetate monohydrate and succinic acid, engineered as a low molecular weight organic gelator. The mechanical...

Thermal Decomposition of Copper Acetate at Various Temperature and Time to form Copper Oxide/Copper Nanoparticles

In the present study, the copper oxide and copper nanoparticles were prepared by thermal decomposition of solid phase copper acetate at various time (1-3 h) and temperature (200-500 ºC). The method is simple, less expensive, avoid toxic solvent as well as avoid use of passivating agents. The FT-IR spectrum of the copper acetate monohydrate (calcined) shows the major changes in absorption peaks associated with methyl, carbon-oxygen double bond, carbon-oxygen single bond and copper-oxygen bond functional groups. Thermogravimetry analysis shows that the copper acetate monohydrate decomposes at about 250 ºC to form copper. The TEM images show a combination of shapes, which includes icosahedrons, truncated cubes and nano-whiskers made from sphere with diameter of 7.43-0.83 nm.

Crystal structure of tetra-μ-acetato-bis[(5-amino-2-methylsulfanyl-1,3,4-thiadiazole-κN 1)copper(II)]

The reaction of 2-methylthio-5-amino-1,3,4-thiadiazole (Me-SNTD; C3H5N3S2) with copper(II) acetate monohydrate [Cu(OAc)2·H2O; C4H8CuO5] resulted in the formation of the title binuclear compound, [Cu2(C2H3O2)4(C3H5N3S2)2] or [Cu2(OAc)4(Me-SNTD)2]. The structure has triclinic (P \overline{1}) symmetry with a crystallographic inversion centre located at the midpoint of the line connecting the Cu atoms in the dimer. These two Cu atoms of the dimer [Cu...Cu = 2.6727 (6) Å] are held together by four carboxylate groups. Each Cu atom is further coordinated to the N atom of an Me-SNTD molecule and exhibits a Jahn–Teller-distorted octahedral geometry. The dimers are connected into infinite chains by hydrogen bonds between the NH (Me-SNTD) and the carboxylate groups of neighbouring molecules, generating an R 2 2(12) ring motif. The molecules are further linked by C—H...π interactions between the thiadiazole rings and the methyl groups of the acetate units.

Copper-Catalyzed NaBAr4-Based N-Arylation of Amines

Using NaBAr4 as an arylating agent, the formation of carbon–heteroatom bonds by a Cham–Lam cross-coupling reaction in the presence of catalytic copper(II) acetate monohydrate in acetonitrile at room temperature under air is described. The investigation of reaction scope suggests that several aliphatic and aromatic amines are compatible. In particular, the reaction of alkylamine and NaBAr4 proceeds smoothly to offer the corresponding products in good to excellent yields.
