Abstract

NaYbN4 crystallizes in the orthorhombic Pnna space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six N1- atoms to form NaN6 octahedra that share corners with two equivalent YbN6 pentagonal pyramids, corners with four equivalent NaN6 pentagonal pyramids, edges with two equivalent YbN6 octahedra, an edgeedge with one NaN6 pentagonal pyramid, and an edgeedge with one YbN6 pentagonal pyramid. There are a spread of Na–N bond distances ranging from 2.44–2.64 Å. In the second Na1+ site, Na1+ is bonded to six N1- atoms to form NaN6 pentagonal pyramids that share corners with four equivalent NaN6 octahedra, an edgeedge with one NaN6 octahedra, edges with two equivalent YbN6 octahedra, and edges with two equivalent YbN6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 6–30°. There are a spread of Na–N bond distances ranging from 2.48–2.66 Å. There are two inequivalent Yb3+ sites. In the first Yb3+ site, Yb3+ is bonded to six N1- atoms to form YbN6 octahedra that share edges with two equivalent NaN6 octahedra, edges with two equivalent NaN6 pentagonal pyramids, and edges with two equivalent YbN6 pentagonal pyramids.
