Materials Data on SrH3C3O7 by Materials Project
SrC3H3O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.59–3.03 Å. There are three inequivalent C3+ sites. In the first C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. In the second C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.27 Å. In the third C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (1.32 Å) C–O bond length. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.69 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.04 Å) and one longer (1.54 Å) H–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sr2+, one C3+, and one H1+ atom. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Sr2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one C3+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+ and one C3+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+, one C3+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+ and one C3+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Sr2+, one C3+, and one H1+ atom.
