Materials Data on K(AuO2)2 by Materials Project
K(AuO2)2 crystallizes in the tetragonal P4_2/mmc space group. The structure is three-dimensional. K1+ is bonded to eight equivalent O2- atoms to form distorted corner-sharing KO8 hexagonal bipyramids. All K–O bond lengths are 2.86 Å. Au+3.50+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Au–O bond lengths are 2.02 Å. O2- is bonded in a distorted see-saw-like geometry to two equivalent K1+ and two equivalent Au+3.50+ atoms.
