Materials Data on Ca2AlH2OF7 by Materials Project
Abstract
Ca2AlH2OF7 crystallizes in the triclinic P-1 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 eight F1- atoms. There are a spread of Ca–F bond distances ranging from 2.24–2.72 Å. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to two equivalent O2- and six F1- atoms. There are one shorter (2.48 Å) and one longer (2.62 Å) Ca–O bond lengths. There are a spread of Ca–F bond distances ranging from 2.25–2.46 Å. There are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded in an octahedral geometry to six F1- atoms. There is two shorter (1.82 Å) and four longer (1.85 Å) Al–F bond length. In the second Al3+ site, Al3+ is bonded in an octahedral geometry to six F1- atoms. There is two shorter (1.79 Å) and four longer (1.86 Å) Al–F bond length. 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 single-bond geometry tomore »
