On the other hand, the literature on fluoride crystallization is scarce, in spite of the recent work on nanosized fluoride particles for applications in optics or catalysisInterest in fluorides is mainly driven by their properties as crystallization agents for the synthesis of zeolites or phosphate-based materials and more recently of metal organic frameworks ° (MOF). Mixed anions (fluoride-phosphate, fluoride-carboxylate...) build three-dimensional 3D open frameworks for gas storage (CO2), catalysis or emerging applications (the symbols OD, ID, 2D, 3D, characteristic of the dimensionality of the frameworks, are used throughout this chapter).

This chapter is devoted to the crystallization of fluoroaluminates. Emphasis is given to hybrid organic-inorganic salts that are synthesized in hydro(solvo)thermal conditions numerous polyanions, derived from the primary building anion (AlFg) , are now evidenced, together with extended one- or two-dimensional architectures. These species are compared with the (Al, F) units that are found in inorganic fluoroaluminates for which a classification of minerals was proposed by F. C. Hawthorne in 1984 .
