Materials Data on KLa(CuO2)2 by Materials Project

KLa(CuO2)2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. K1+ is bonded to eight equivalent O2- atoms to form distorted edge-sharing KO8 hexagonal bipyramids. All K–O bond lengths are 2.88 Å. La3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All La–O bond lengths are 2.52 Å. 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 two equivalent K1+, two equivalent La3+, and two equivalent Cu2+ atoms to form a mixture of distorted edge, face, and corner-sharing OK2La2Cu2 octahedra. The corner-sharing octahedra tilt angles range from 0–67°.
