CsAsO4 crystallizes in the tetragonal I-42d space group. Cs(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. As(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one As(1) atom.
CsAsO4 crystallizes in the tetragonal I-42d space group. Cs(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. There are four shorter (3.08 Å) and four longer (3.23 Å) Cs(1)-O(1) bond lengths. As(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. All As(1)-O(1) bond lengths are 1.74 Å. O(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one As(1) atom.
