Materials Data on ScH3Br3N by Materials Project

ScNH3Br3 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one ScNH3Br3 ribbon oriented in the (1, 1, -1) direction. there are two inequivalent Sc3+ sites. In the first Sc3+ site, Sc3+ is bonded to one N3- and five Br1- atoms to form edge-sharing ScBr5N octahedra. The Sc–N bond length is 2.29 Å. There are a spread of Sc–Br bond distances ranging from 2.55–2.76 Å. In the second Sc3+ site, Sc3+ is bonded to one N3- and five Br1- atoms to form edge-sharing ScBr5N octahedra. The Sc–N bond length is 2.29 Å. There are a spread of Sc–Br bond distances ranging from 2.55–2.75 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Sc3+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. In the second N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Sc3+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are six inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in an L-shaped geometry to two Sc3+ atoms. In the second Br1- site, Br1- is bonded in a water-like geometry to two equivalent Sc3+ atoms. In the third Br1- site, Br1- is bonded in an L-shaped geometry to two Sc3+ atoms. In the fourth Br1- site, Br1- is bonded in an L-shaped geometry to two equivalent Sc3+ atoms. In the fifth Br1- site, Br1- is bonded in a single-bond geometry to one Sc3+ atom. In the sixth Br1- site, Br1- is bonded in a single-bond geometry to one Sc3+ atom.
