Materials Data on Na3PSO3 by Materials Project

Abstract

Na3PO3S crystallizes in the trigonal R3c space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to two equivalent S2- and four equivalent O2- atoms. There are one shorter (2.95 Å) and one longer (3.03 Å) Na–S bond lengths. There are a spread of Na–O bond distances ranging from 2.38–2.59 Å. P5+ is bonded in a distorted tetrahedral geometry to one S2- and three equivalent O2- atoms. The P–S bond length is 2.10 Å. All P–O bond lengths are 1.55 Å. S2- is bonded in a 7-coordinate geometry to six equivalent Na1+ and one P5+ atom. O2- is bonded to four equivalent Na1+ and one P5+ atom to form a mixture of distorted edge and corner-sharing ONa4P trigonal bipyramids.
