Materials Data on Ca3Al2H6S(OF)8 by Materials Project
Abstract
Ca3Al2H6S(OF)8 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to four O2- and four F1- atoms. There are two shorter (2.64 Å) and two longer (2.66 Å) Ca–O bond lengths. There are two shorter (2.29 Å) and two longer (2.32 Å) Ca–F bond lengths. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to three O2- and five F1- atoms. There are a spread of Ca–O bond distances ranging from 2.51–2.57 Å. There are a spread of Ca–F bond distances ranging from 2.34–2.44 Å. Al3+ is bonded to two equivalent O2- and four F1- atoms to form edge-sharing AlO2F4 octahedra. There is one shorter (1.89 Å) and one longer (1.90 Å) Al–O bond length. There are a spread of Al–F bond distances ranging from 1.80–1.88 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.69 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted single-bond geometrymore »
