Materials Data on YbTiO3 by Materials Project

Abstract

YbTiO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Yb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Yb–O bond distances ranging from 2.31–2.67 Å. Ti4+ is bonded to six O2- atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 28–29°. There are a spread of Ti–O bond distances ranging from 1.96–1.98 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Yb2+ and two equivalent Ti4+ atoms to form distorted corner-sharing OYb2Ti2 tetrahedra. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Yb2+ and two equivalent Ti4+ atoms.
