Materials Data on Rb3Sc(HO)6 by Materials Project
Rb3Sc(HO)6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Rb1+ is bonded in a 12-coordinate geometry to four equivalent H1+ and eight equivalent O2- atoms. There are two shorter (3.00 Å) and two longer (3.08 Å) Rb–H bond lengths. There are a spread of Rb–O bond distances ranging from 2.88–3.22 Å. Sc3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Sc–O bond lengths are 2.16 Å. H1+ is bonded in a single-bond geometry to two equivalent Rb1+ and one O2- atom. The H–O bond length is 0.97 Å. O2- is bonded in a distorted single-bond geometry to four equivalent Rb1+, one Sc3+, and one H1+ atom.
