Abstract

A caesium lutetium(III) silicate, Cs₃LuSi₃O₉, was synthesized by heating a pelletized mixture of Cs₂CO₃, Lu₂O₃and SiO₂at 1273 K. Single crystals of the title compound were grown in a melted area of the pellet. Cs₃LuSi₃O₉is a single-chain silicate (ortho rhom bic space group Pna2₁) with a chain periodicity of six and is isostructural with Cs₃RE ^IIIGe₃O₉(RE = Pr, Nd and Sm-Yb). The two symmetry-dependent [Si₆O₁₈]^12-chains in the unit cell lie parallel to the [011] direction. The Lu³⁺ions are octa hedrally coordinated by O atoms of the silicate chains, generating a three-dimensional framework. Cs⁺ions are located in the voids in the framework.
