Abstract
Crystals of a new titanosilicate phase, Cs2TiSi6O15, were grown from a cesium vanadate flux. The compound has monoclinic symmetry, space groupC2/c, witha=13.386(5),b=7.423(3),c=15.134(5) Å,β=107.71(3)°,Z=4. The crystal structure was solved using single crystal X-ray data (MoKαradiation) and refined toR(F)=0.039 for 1874 unique reflections. In the structure, isolated titanium-centred octahedra and silica-centred tetrahedra share all corners to form an open framework structure containing large cavities in which the cesium ions are located. Each cavity is bound by three 5-rings, two 6-rings, and two 8-rings. The cavities are linked via the 8-rings into channels parallel to [101]. The cesium ions occur in pairs along the channels, separated by 3.765(2) Å.
