Cerium(IV) fluoride and fluoride-arsenate frameworks

Abstract

Five new cerium (IV) fluoride and fluoridearsenate framework structures have been synthesised hydrothermally using CeF4 as a fluoride source. Cs[Ce2F8[F·H2O]] (I) consists of layers, formed from linked Ce(F,O)n polyhedra cross-linked by hydrogen bonding that defines large channels containing the caesium ions. [(NH4)5(H2O)2][Ce4(AsO4)6(H2O)F3] (II), has an open framework structure with large channels filled with NH4+ cations and H2O molecules. Ce[AsO4]F (III) and Ce[AsO4]F[H2O] (IV) exhibit two types of bridging (Ce–O–Ce and Ce–F–Ce) bonds between Ce(O,F)n polyhedra, and (NH4)[CeF2(AsO4)] (V), is isostructural with the previously reported fluoride-phosphate (NH4)[CeIVF2(PO4)] (R. B. Yu, D. Wang, T. Takei, N. Kumada, H. Koizumi and N. Kinomura, J. Solid State Chem., 2001, 157, 180).
