Perovskite-related LaTiO3.41

Crystals of pentalanthanum pentatitanium heptadecaoxide (La5Ti5O17 with 0.3% oxygen excess, or LaTiO3.41) have been synthesized by floating‐zone melting, and the structure has been solved using single‐crystal X‐ray diffraction intensities. The monoclinic (P21/c) structure consists of perovskite‐lik...

Zusammenfassung:	Crystals of pentalanthanum pentatitanium heptadecaoxide (La5Ti5O17 with 0.3% oxygen excess, or LaTiO3.41) have been synthesized by floating‐zone melting, and the structure has been solved using single‐crystal X‐ray diffraction intensities. The monoclinic (P21/c) structure consists of perovskite‐like slabs of vertex‐sharing TiO6 octahedra, which are separated by additional oxygen layers. The slabs are five octahedra wide. Due to the adjustment of the TiO6 octahedra to meet the coordination requirements of the La3+ cations, a superstructure develops along the a axis.
