Materials Data on TaBr5N2 by Materials Project
(Ta2N)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 Ta2N clusters. In each Ta2N cluster, Ta5+ is bonded in a single-bond geometry to one N3- atom. The Ta–N bond length is 1.89 Å. N3- is bonded in a linear geometry to two equivalent Ta5+ atoms.
