Materials Data on RbMgP(H6O5)2 by Materials Project
RbMgP(H6O5)2 crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. Rb1+ is bonded in a 1-coordinate geometry to five O2- atoms. There are a spread of Rb–O bond distances ranging from 2.91–3.20 Å. Mg2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.09–2.19 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.55 Å) and three longer (1.56 Å) P–O bond length. There are seven inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.70 Å) H–O bond length.
