Materials Data on InC4Br7N4 by Materials Project

Abstract

InBr6C4N4Br crystallizes in the monoclinic P2/c space group. The structure is zero-dimensional and consists of four C4N4Br clusters and four InBr6 clusters. In each C4N4Br cluster, there are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. In the second C4+ site, C4+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a single-bond geometry to one C4+ and one Br1- atom. The N–Br bond length is 3.32 Å. In the second N3- site, N3- is bonded in a single-bond geometry to one C4+ and one Br1- atom. The N–Br bond length is 3.40 Å. Br1- is bonded in a distorted rectangular see-saw-like geometry to four N3- atoms. In each InBr6 cluster, In3+ is bonded in an octahedral geometry to six Br1- atoms. There are two shorter (2.67 Å) and four longer (2.68 Å) In–Br bond lengths. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In the third Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom.
