Quaternary CrSBr 0.67 Cl 0.33 was obtained as black needles by heating chromium powder with a mixture of S 2 Br 2 and S 2 Cl 2 at 1273 K. It was found from X-ray precession photographs and an X-ray diffraction powder structure determination to be iso

Raman spectra of spinel-type cobalt chromium indium sulfide solid solutions are presented in order to establish the decomposition of these solid solutions to chromium-rich and indium-rich sulfides on annealing at 873 and 1073 K. The results suggest t

Infrared spectra (IR, FIR, DRIFT, 90 and 295 K) and DSC measurements of the various polymorphs of iron oxide hydroxide, viz. goethite (α), akaganeite (β), lepidocrocite (γ), and feroxyhite (δ), and of deuterated specimens are reported. They are d

The order-disorder phase transitions of spinel-type (I) chlorides Li2MIICl4 (MII =Mg, Mn, Cd) to Li2MnBr4cF56 (II) and disordered, deficient NaCl structure (III) at elevated temperatures are characterized by X-ray diffraction, dilatometry, thermoanal

Lattice dynamical calculations of spinel-type ZnCr 2 O 4 have been performed using various potential models (short-range, rigid-ion, polarizable-ion). The potential energy is mainly controlled by Cr-O (octahedron) and Zn-O (tetrahedron) interactions

γ-Cd(OH)2 was reported to be an aquoxy-hydroxide of formulae: Cd2O(OH)2 · H2O (Riou et al., 1990). From IR and Raman spectroscopic studies, it is revealed that γ-Cd(OH)2 is really a common hydroxide. There are three different OH− ions. One forms

The dynamic behaviour of water molecules in solid hydrates is exemplarily studied by means of IR and Raman spectroscopic measurements of the isomorphic M(XO 3 ) 2 ·H 2 O (M = Ba, Sr, Pb; X = Cl, Br, I). The halfwidths of the ν OD bands of matrix is
