Abstract

The syntheses and characterisation of a new family of isostructural mixed-metal selenites based on the zemannite-type framework are described. These BaM2(SeO3)3·3H2O phases are built up from three-dimensional networks of MO6 (M = Co, Ni, Mn, Mg) octahedra and SeO3 pyramids. The octahedral groups form isolated M2O9 face-sharing pairs, which are linked by the selenite anions into a three-dimensional anionic framework. The framework encapsulates one-dimensional 12-ring channels occupied by the barium cations and water molecules. There are two types of channels: in one, the cations and water molecules are well ordered, and the channels are fully occupied; in the other, the same species are disordered, and the channels are partially occupied. There is little if any evidence of zeolitic reversible de/rehydration and cation ion-exchange behaviour for these materials.
