Materials Data on KBiO2 by Materials Project
KBiO2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. K1+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing KO6 octahedra. The corner-sharing octahedral tilt angles are 23°. There are a spread of K–O bond distances ranging from 2.75–2.96 Å. Bi3+ is bonded in a see-saw-like geometry to four equivalent O2- atoms. There are two shorter (2.13 Å) and two longer (2.37 Å) Bi–O bond lengths. O2- is bonded to three equivalent K1+ and two equivalent Bi3+ atoms to form a mixture of distorted edge and corner-sharing OK3Bi2 trigonal bipyramids.
