Materials Data on La2CuO4 by Materials Project
La2CuO4 is (La,Ba)CuO4-like structured and crystallizes in the orthorhombic Cmce 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 2.31–2.87 Å. Cu2+ is bonded to six O2- atoms to form corner-sharing CuO6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are four shorter (1.91 Å) and two longer (2.44 Å) Cu–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to five equivalent La3+ and one Cu2+ atom. In the second O2- site, O2- is bonded to four equivalent La3+ and two equivalent Cu2+ atoms to form a mixture of distorted corner, edge, and face-sharing OLa4Cu2 octahedra. The corner-sharing octahedral tilt angles are 0°.
