Abstract

AuBr4Co(NBr)2(N2)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four nitrogen molecules, two AuBr4 clusters, and two Co(NBr)2 clusters. In each AuBr4 cluster, Au5+ is bonded in a square co-planar geometry to four Br1- atoms. There are two shorter (2.48 Å) and two longer (2.52 Å) Au–Br bond lengths. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Au5+ atom. In the second Br1- site, Br1- is bonded in a distorted single-bond geometry to one Au5+ atom. In each Co(NBr)2 cluster, Co3+ is bonded in a linear geometry to two equivalent N+0.33- atoms. Both Co–N bond lengths are 1.66 Å. N+0.33- is bonded in a distorted single-bond geometry to one Co3+ and one Br1- atom. The N–Br bond length is 1.77 Å. Br1- is bonded in a distorted single-bond geometry to one N+0.33- atom.
