Title: Materials Data on SiH2O by Materials Project

Abstract

SiH2O crystallizes in the monoclinic Cm space group. The structure is two-dimensional and consists of one SiH2O sheet oriented in the (0, 0, 1) direction. Si4+ is bonded to three equivalent H1- and one O2- atom to form distorted corner-sharing SiH3O trigonal pyramids. There is one shorter (1.73 Å) and two longer (1.99 Å) Si–H bond length. The Si–O bond length is 1.69 Å. 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 trigonal planar geometry to three equivalent Si4+ atoms. O2- is bonded in a bent 120 degrees geometry to one Si4+ and one H1- atom.
