Materials Data on Nd2S4N2O17 by Materials Project

Nd2S4O17N2 crystallizes in the triclinic P1 space group. The structure is three-dimensional and consists of two ammonia molecules and one Nd2S4O17 framework. In the Nd2S4O17 framework, there are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Nd–O bond distances ranging from 2.44–2.70 Å. In the second Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.42–2.56 Å. There are four inequivalent S6+ sites. In the first S6+ site, S6+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. All S–O bond lengths are 1.47 Å. In the second S6+ site, S6+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.48 Å. In the third S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.48–1.52 Å. In the fourth S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.47–1.54 Å. There are seventeen inequivalent O2- sites.
