Materials Data on La2AgO4 by Materials Project

La2AgO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. La3+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.17–3.01 Å. Ag2+ is bonded to six O2- atoms to form corner-sharing AgO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.06 Å) and two longer (2.53 Å) Ag–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to five equivalent La3+ and one Ag2+ atom. In the second O2- site, O2- is bonded to four equivalent La3+ and two equivalent Ag2+ atoms to form a mixture of distorted edge, face, and corner-sharing OLa4Ag2 octahedra. The corner-sharing octahedral tilt angles are 0°.
