Materials Data on Rb2SnO12 by Materials Project
Rb2SnO12 crystallizes in the trigonal P-3c1 space group. The structure is two-dimensional and consists of two Rb2SnO12 sheets oriented in the (0, 0, 1) direction. Rb is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Rb–O bond distances ranging from 2.97–3.14 Å. Sn is bonded in an octahedral geometry to six equivalent O atoms. All Sn–O bond lengths are 2.22 Å. There are two inequivalent O sites. In the first O site, O is bonded in a distorted T-shaped geometry to two equivalent Rb and one O atom. The O–O bond length is 1.33 Å. In the second O site, O is bonded in a 2-coordinate geometry to one Rb, one Sn, and one O atom.
