Materials Data on Ba14Na7CaN6 by Materials Project
Na7Ba14CaN6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. there are three inequivalent Na sites. In the first Na site, Na is bonded in a 7-coordinate geometry to one Na and six Ba atoms. The Na–Na bond length is 3.61 Å. There are three shorter (4.03 Å) and three longer (4.19 Å) Na–Ba bond lengths. In the second Na site, Na is bonded in a 10-coordinate geometry to two equivalent Na and eight Ba atoms. Both Na–Na bond lengths are 3.77 Å. There are a spread of Na–Ba bond distances ranging from 4.17–4.52 Å. In the third Na site, Na is bonded in a 8-coordinate geometry to five Na and three equivalent Ba atoms. The Na–Na bond length is 3.58 Å. All Na–Ba bond lengths are 4.32 Å. There are three inequivalent Ba sites. In the first Ba site, Ba is bonded in a single-bond geometry to four Na and one N atom. The Ba–N bond length is 2.50 Å. In the second 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 2.79 Å. In the third 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 2.77–2.80 Å. Ca is bonded in an octahedral geometry to six equivalent N atoms. All Ca–N bond lengths are 2.57 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°.
