The first ternary lanthanide telluride-bromide La3Te4Br was obtained from a mixture of LaTe and LaBr3 (in the presence of iridium) in a sealed tantalum container at elevated temperatures. The crystal structure (orthorhombic, Pnma, a = 1634.3(2), b =...

KNaNbOF₅ and KNaMO₂F₄ (M = Mo⁶⁺, W⁶⁺), three new layered oxide-fluoride perovskites with the general formula ABB’X₆, form from the combination of a second-order Jahn-Teller d⁰ transition metal and an alkali metal (Na⁺) on the B-site. Alternating laye...

The majority of the earth’s crust is made up of crystalline material. The research areas of mineralogy, petrology, chimie minerále (inorganic chemistry) and, of course, crystallography outgrew from the fascination of mankind with the color and symmet...
