Materials Data on MgH4(ClO)2 by Materials Project

MgH4(OCl)2 crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two MgH4(OCl)2 ribbons oriented in the (0, 0, 1) direction. Mg2+ is bonded to two equivalent O2- and four equivalent Cl1- atoms to form edge-sharing MgCl4O2 octahedra. Both Mg–O bond lengths are 2.04 Å. There are two shorter (2.53 Å) and two longer (2.59 Å) Mg–Cl bond lengths. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. O2- is bonded in a distorted trigonal planar geometry to one Mg2+ and two equivalent H1+ atoms. Cl1- is bonded in an L-shaped geometry to two equivalent Mg2+ atoms.
