Research output: Contribution to journalArticlepeer-review


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.
