A new strontium lithium titanate with composition SrLi2Ti6O14 has been discovered in the ternary system SrO - Li2O - TiO2. Single crystals of this compound have been grown by the flux method. The structure of SrLi2Ti6O14 has been solved using X-ray data (Mo-Kÿ radiation, orthorhombic, space group Cmca, Z = 8, with a = 16.570(5), b = 11.150(2), c = 11.458(2) A˚ , R1 = 0.039 (wR2 = 0.087)). The crystal structure is built by edge and corner sharing TiO6 octahedra which form layers parallel to the (100) plane. Consecutive layers [deduced from a mirror plane parallel to (100)] are linked by common corners in the a direction. Lithium atoms in tetrahedral coordination occupy vacancies of the framework of titanium octahedra, while strontium atoms lie in 11-coordinated sites between two successive layers.< Réduire
