Materials Data on Li2CuO2 by Materials Project
Li2CuO2 is Spinel-like structured and crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Li1+ is bonded to four equivalent O2- atoms to form a mixture of distorted edge and corner-sharing LiO4 trigonal pyramids. There is two shorter (1.95 Å) and two longer (1.99 Å) Li–O bond length. Cu2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.98 Å. O2- is bonded to four equivalent Li1+ and two equivalent Cu2+ atoms to form a mixture of edge and corner-sharing OLi4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 0–36°.
