Abstract

Five new cerium (IV) fluoride and fluoride–arsenate 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)
