Materials Data on H2SO4 by Materials Project

Abstract

H2SO4 crystallizes in the monoclinic C2 space group. The structure is two-dimensional and consists of two H2SO4 sheets oriented in the (0, 0, 1) direction. H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.66 Å) H–O bond length. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.44 Å) and two longer (1.56 Å) S–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one H1+ and one S6+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S6+ atom.
