Materials Data on Na2Sn(HO)6 by Materials Project
Na2Sn(OH)6 crystallizes in the trigonal R-3 space group. The structure is two-dimensional and consists of three Na2Sn(OH)6 sheets oriented in the (0, 0, 1) direction. Na1+ is bonded in a trigonal non-coplanar geometry to three equivalent O2- atoms. All Na–O bond lengths are 2.24 Å. Sn4+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Sn–O bond lengths are 2.09 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. O2- is bonded in a distorted single-bond geometry to one Na1+, one Sn4+, and one H1+ atom.
