Materials Data on KAsO4 by Materials Project
KAsO4 is Zircon-like structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. K is bonded in a 8-coordinate geometry to eight equivalent O atoms. There are four shorter (2.78 Å) and four longer (2.96 Å) K–O bond lengths. As is bonded in a tetrahedral geometry to four equivalent O atoms. All As–O bond lengths are 1.74 Å. O is bonded in a 1-coordinate geometry to two equivalent K and one As atom.
