Laser pulse photolysis was used to study the nature and reactions of intermediates in the photochemistry of the flat dithiocarbamate complex Cu(Et(2)dtc)(2) in CCl(4). A nanosecond laser pulse (355 nm) is shown to induce intermediate absorption bands of bivalent copper complex whose coordination sphere contains a dithiocarbamate radical Et(2)dtc(•) and a chloride ion at the axial position ([(Et(2)dtc)Cu(Et(2)dtc(•))Cl(a)]). At room temperature during some microseconds after the laser pulse, this intermediate interacts with the initial complex to form presumably a dimer [Cu(2)(Et(2)dtc)(3)(Et(2)dtc(•))Cl]. The latter vanishes in the second-order reaction. Analysis of kinetic and spectral features gives the arguments for the formation of a cluster [Cu(2)(Et(2)dtc)(3)Cl-tds-Cu(2)(Et(2)dtc)(3)Cl], which produces a new absorption band at 345 nm. The cluster decomposes in ∼5 ms into final products, a binuclear complex [Cu(2)(Et(2)dtc)(3)Cl] and tetraethylthiuramdisulfide (Et(4)tds).

Two new isostructural complexes, dibromobis(1‐ethyltetrazole)copper(II) (1) and dibromobis(1‐hexyltetrazole)copper(II) (2), have been synthesised. Each bromine atom in the crystal structure of 1 and 2 is bonded to two copper atoms to give rise to a polymeric corrugated network. The polymeric layers are distinctly separated by tetrazole ligands. Both solids exhibit a phase transition to the ferromagnetic state with Curie temperatures of 8.5 K and 8.9 K for 1 and 2, respectively, and a strong anisotropy of the magnetic susceptibility below the ordering temperature. The easy magnetisation axis lies along the monoclinic axis, and the hard magnetisation axis is orthogonal to the polymeric layers. Effective anisotropy fields were estimated as (720–3020 Oe).

A simple method for formation of CdS nanoparticles on the surface of carbon nanotubes (CNTs) aligned perpendicularly to the silicon substrate has been developed. The size and shape of the CdS nanoparticles were found to depend on the temperature of a solution containing CdCl(2), (NH(2))(2)CS, and NH(3) and the deposition time. Electron microscopy study revealed a direct contact between CdS nanoparticles and CNT surface. X-Ray photoelectron spectroscopy examination of the CdS/CNT hybrid material detected surface oxidation of the grown nanoparticles.
