Materials Data on K2Sn(HO)6 by Materials Project
K2Sn(OH)6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. K1+ is bonded in a 9-coordinate geometry to three equivalent H1+ and six equivalent O2- atoms. All K–H bond lengths are 2.74 Å. There are three shorter (2.80 Å) and three longer (3.02 Å) K–O bond lengths. Sn4+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Sn–O bond lengths are 2.11 Å. H1+ is bonded in a single-bond geometry to one K1+ and one O2- atom. The H–O bond length is 0.99 Å. O2- is bonded in a distorted single-bond geometry to two equivalent K1+, one Sn4+, and one H1+ atom.
