Materials Data on Mg(HO)2 by Materials Project
Mg(OH)2 crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one Mg(OH)2 sheet oriented in the (0, 0, 1) direction. Mg2+ is bonded to six equivalent O2- atoms to form edge-sharing MgO6 octahedra. All Mg–O bond lengths are 2.11 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 three equivalent Mg2+ and one H1+ atom.
