(NMe4)2CuBrnC14-n and (NEt4)nCuBrnCl44-n (n = 1, 2, 3) have been prepared and characterized by X-ray powder diffraction and far-infrared spectroscopy. The tetramethylammonium compounds are isomorphous with each other and with the corresponding compounds where n = 0, 4. The tetraethylammonium compounds constitute another isomorphous series. All the compounds apparently contain discrete CuBrnCI4-n2- anions, with flattened tetrahedral configurations.

Zinc Sulfide Nanoparticles

AbstractZinc sulfide nanoparticles, prepared employing a non-equilibrium route, are investigated for surface related effects. Water has been shown to induce a structural transformation in nanoparticles prepared this way, which is not related to their particle size. Employing Fourier transform infrared spectroscopy and x-ray powder diffraction, we show here the importance of S-H interaction in the buildup to the final ZnS structure of these nanoparticles. These particles hold promise as water sensors.

The thermal behaviour of [Ba(HOC2H4OH)2Ge(OC2H4O)3] (2) as a BaGeO3 precursor,and its phase evolution during thermal decomposition in different atmospheres are described herein.The precursor complex decomposes in air to a finely divided mixture of BaCO3 and GeO2, whichsubsequently reacts above 650 °C to orthorhombic BaGeO3, transforming above 800 °C tohexagonal BaGeO3. The shrinkage behaviour of BaGeO3 compacts made from the as-preparedpowders as well as from conventional mixed-oxide powders has been investigated. The sampleswere characterised by Fourier transformed infrared spectroscopy (FT-IR), X-ray powder diffraction(XRD), dilatometric measurements and thermoanalytic investigations (TG/DTA).
