    Dans le cadre d’une étude générale des systèmes magnétiques de basse dimensionnalité rencontrés dans les fluorures, nous décrivons ici de nouveaux composés isostructuraux de l’usovite Ba2CaMgAl2F14 et de la jarlite Sr6Na2MgAl6F32(OH)2. D’un point de vue magnétique, ces fluorures présentent un comportement caractéristique de chaînes ferrimagnétiques, ou, pour certains, de clusters ferrimagnétiques. Nous nous sommes efforcés de corréler structure et propriétés magnétiques, et de paramétrer ces propriétés grâce à des modèles théoriques originaux

    importance in the development of many new technologies, andare impacting various key points of modern life, that is, energyproduction and storage, microelectronics and photonics,catalysis, automotive, building, etc. Many research fields andapplications are indeed concerned by a better knowledge of therelationships occurring between the structure of suchcompounds and some pertinent physical properties. ThisReview deals with the structural chemistry of solid-stateinorganic fluorides and oxide-fluorides, mostly transitionmetal-based, including rare-earth elements. Such a Review hasnot been published for a long time.1 Articles that recentlyappeared on inorganic fluorinated compounds were mostlyfocused on material science characteristics: morphology, surfacefunctionalization, nanostructuration of the materials andapplications, rather than on the description of characteristicstructural features.2−5 Detailed reviews focused on rare earthbasedinorganic fluorides have also appeared some yearsago..
