Materials Data on Na2LaPS2O7 by Materials Project
Abstract
Na2LaPSO7S crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four hydrogen sulfide molecules and one Na2LaPSO7 framework. In the Na2LaPSO7 framework, there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.44–2.58 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.23–2.95 Å. In the third Na1+ site, Na1+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.28–2.41 Å. La3+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of La–O bond distances ranging from 2.32–2.35 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent NaO6 octahedra. The corner-sharing octahedra tilt angles range from 17–41°. There is three shorter (1.56 Å) and one longer (1.57 Å) P–O bond length. S2+ is bonded in a trigonal non-coplanar geometry to threemore »
