Materials Data on La2ZnRhO6 by Materials Project
La2ZnRhO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.40–2.80 Å. Rh4+ is bonded to six O2- atoms to form RhO6 octahedra that share corners with six equivalent ZnO6 octahedra. The corner-sharing octahedral tilt angles are 31°. There are a spread of Rh–O bond distances ranging from 2.03–2.05 Å. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six equivalent RhO6 octahedra. The corner-sharing octahedral tilt angles are 31°. There are a spread of Zn–O bond distances ranging from 2.09–2.14 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent La3+, one Rh4+, and one Zn2+ atom to form distorted corner-sharing OLa2ZnRh tetrahedra. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one Rh4+, and one Zn2+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one Rh4+, and one Zn2+ atom.
