Materials Data on NbBr5N2 by Materials Project
(Nb2N)2(N2)3(Br)20 crystallizes in the tetragonal P4/mnc space group. The structure is zero-dimensional and consists of six ammonia molecules, twenty hydrobromic acid molecules, and two Nb2N clusters. In each Nb2N cluster, Nb5+ is bonded in a single-bond geometry to one N3- atom. The Nb–N bond length is 1.88 Å. N3- is bonded in a linear geometry to two equivalent Nb5+ atoms.
