Materials Data on K3SbO3 by Materials Project

K3SbO3 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a distorted T-shaped geometry to three equivalent O2- atoms. All K–O bond lengths are 2.64 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (2.79 Å) and three longer (3.02 Å) K–O bond lengths. In the third K1+ site, K1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (2.81 Å) and three longer (2.99 Å) K–O bond lengths. Sb3+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent O2- atoms. All Sb–O bond lengths are 1.97 Å. O2- is bonded in a 6-coordinate geometry to five K1+ and one Sb3+ atom.
