Title: Materials Data on Ba14Na8CaN6 by Materials Project

Abstract

Na8Ba14CaN6 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are four inequivalent Na sites. In the first Na site, Na is bonded in a distorted body-centered cubic geometry to five Na and three equivalent Ba atoms. There are a spread of Na–Na bond distances ranging from 3.70–3.95 Å. All Na–Ba bond lengths are 4.18 Å. In the second Na site, Na is bonded in a 8-coordinate geometry to two equivalent Na and six Ba atoms. There are four shorter (4.40 Å) and two longer (4.42 Å) Na–Ba bond lengths. In the third Na site, Na is bonded in a 7-coordinate geometry to one Na and six Ba atoms. There are three shorter (4.14 Å) and three longer (4.33 Å) Na–Ba bond lengths. In the fourth Na site, Na is bonded in a 6-coordinate geometry to six equivalent Ba atoms. All Na–Ba bond lengths are 4.09 Å. There are three inequivalent Ba sites. In the first Ba site, Ba is bonded in a 3-coordinate geometry to two Na and three equivalent N atoms. There are a spread of Ba–N bond distances ranging from 2.77–2.82 Å. In the second Ba site, Ba is bonded in a single-bond geometrymore » to four Na and one N atom. The Ba–N bond length is 2.50 Å. In the third Ba site, Ba is bonded in a 3-coordinate geometry to three equivalent Na and three equivalent N atoms. All Ba–N bond lengths are 2.76 Å. Ca is bonded in an octahedral geometry to six equivalent N atoms. All Ca–N bond lengths are 2.56 Å. N is bonded to five Ba and one Ca atom to form a mixture of distorted face and corner-sharing NBa5Ca octahedra. The corner-sharing octahedral tilt angles are 0°.« less
