“…[48] Two-dimensional transition-metal silicates have been prepared in the presence of alkali-metal cations. [49,50] [50] The zirconium octahedra and SiO 4 tetrahedra are connected to form the layered structure. The Na + ions, situated in between the layers, can be ion-exchanged by, for example, Li + , K + , Cs + , Ca 2+ , Ba 2+ and Sr 2+ ions.…”

Inorganic framework solids are no longer limited to just the silicates and phosphates. Recent research has revealed that carboxylates, arsenates, sulfates, selenates, selenites, germanates, phosphites can also form such structures. One of the emerging areas combines the rich coordination chemistry of the central metal ions of many of these structures with the flexibility and functionality of the organic linkers to give rise to organic-inorganic hybrid compounds. The compounds of the transition-metals appear to provide many variations arising from their coordination preferences, ligand geometry, and the valence state. In addition, the combination of the magnetic nature of the transition metal center with the channel structure of open frameworks suggests interesting potential applications. In this Review the synthesis, structures and properties of the various transition-metal open-framework compounds are discussed.

“…The other cation site is occupied by 33% K ϩ and 67% Na ϩ and is located in the large channel near the wall. [46,60] The crystal structure of AM-4 is built from TiO 6 (M) octahedra and SiO 4 (T) tetrahedra that form layers perpendicular to [001]. The mineral occurs in two polytipic modifications, orthorhombic (penkvilksite-2O) and monoclinic (penkvilksite-1M).…”

Stable microporous materials, such as zeolites, are extremely important for applications in catalysis, adsorption, ion‐exchange, and separation. In this review we describe a new class of stable microporous materials that involves novel mixed octhaedral‐tetrahedral framework oxides. The archetypal material is based on titanosilicates, although there is tremendous scope for introducing many other transition metals. These materials not only have potential novel applications in the fields normally associated with zeolites but also possible applications in the areas of optoelectronics, nonlinear optics, batteries, magnetic materials and sensors.

“…Since titanosilicates with kukisvumite-like structures can be prepared under laboratory conditions (Dadachov et al 1997), their acid treatment may lead to formation of specific layered protonated titanosilicates that may serve as a precursor for fabrication of novel titanosilicate nanomaterials.…”
