Abstract

Na3W2N5 is Chalcostibite-like structured and crystallizes in the tetragonal I4_1 space group. The structure is three-dimensional. there are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five N3- atoms. There are a spread of Na–N bond distances ranging from 2.48–2.77 Å. In the second Na1+ site, Na1+ is bonded in a distorted trigonal non-coplanar geometry to three N3- atoms. There are a spread of Na–N bond distances ranging from 2.35–2.61 Å. In the third Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six N3- atoms. There are a spread of Na–N bond distances ranging from 2.52–2.96 Å. In the fourth Na1+ site, Na1+ is bonded in a square co-planar geometry to four N3- atoms. There are two shorter (2.36 Å) and two longer (2.41 Å) Na–N bond lengths. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to four N3- atoms to form corner-sharing WN4 tetrahedra. There are a spread of W–N bond distances ranging from 1.77–1.98 Å. In the second W6+ site, W6+ is bonded to four N3- atoms to form corner-sharing WN4 tetrahedra. There are a spread of W–N bond distances rangingmore »« less
