(N2)3(Bi2Br9)2 is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is zero-dimensional and consists of six ammonia atoms and two Bi2Br9 clusters. In each Bi2Br9 cluster, Bi(1) is bonded to three equivalent Br(1) and three equivalent Br(2) atoms to form face-sharing BiBr6 octahedra. There are two inequivalent Br sites. In the first Br site, Br(2) is bonded in a single-bond geometry to one Bi(1) atom. In the second Br site, Br(1) is bonded in an L-shaped geometry to two equivalent Bi(1) atoms.

In each Bi2Br9 cluster, Bi(1) is bonded to three equivalent Br(1) and three equivalent Br(2) atoms to form face-sharing BiBr6 octahedra. All Bi(1)-Br(1) bond lengths are 2.91 Å. All Bi(1)-Br(2) bond lengths are 2.62 Å. There are two inequivalent Br sites. In the first Br site, Br(2) is bonded in a single-bond geometry to one Bi(1) atom. In the second Br site, Br(1) is bonded in an L-shaped geometry to two equivalent Bi(1) atoms.
