Materials Data on K2SnO6 by Materials Project
K2SnO6 crystallizes in the trigonal R-3 space group. The structure is two-dimensional and consists of three K2SnO6 sheets oriented in the (0, 0, 1) direction. K is bonded in a 6-coordinate geometry to six equivalent O atoms. There are three shorter (2.80 Å) and three longer (2.83 Å) K–O bond lengths. Sn is bonded in a distorted octahedral geometry to six equivalent O atoms. All Sn–O bond lengths are 2.05 Å. O is bonded in a 3-coordinate geometry to two equivalent K and one Sn atom.
