Materials Data on KRuO4 by Materials Project
KRuO4 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. K is bonded in a 8-coordinate geometry to eight equivalent O atoms. There are four shorter (2.85 Å) and four longer (2.91 Å) K–O bond lengths. Ru is bonded in a tetrahedral geometry to four equivalent O atoms. All Ru–O bond lengths are 1.75 Å. O is bonded in a distorted single-bond geometry to two equivalent K and one Ru atom.
