Materials Data on KLiO by Materials Project

KLiO crystallizes in the orthorhombic Cmce space group. The structure is two-dimensional and consists of two KLiO sheets oriented in the (0, 1, 0) direction. K1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are two shorter (2.85 Å) and two longer (2.88 Å) K–O bond lengths. Li1+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. There are a spread of Li–O bond distances ranging from 1.89–1.93 Å. O2- is bonded in a 3-coordinate geometry to four equivalent K1+ and three equivalent Li1+ atoms.
