Materials Data on RbH3O2 by Materials Project

RbH3O2 crystallizes in the orthorhombic Cmc2_1 space group. The structure is two-dimensional and consists of two RbH3O2 sheets oriented in the (0, 1, 0) direction. Rb1+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. There are one shorter (2.95 Å) and two longer (3.00 Å) Rb–O bond lengths. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.59 Å) H–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to three equivalent Rb1+ and two equivalent H1+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three H1+ atoms.
