The structure described by Ta2N3B crystallizes in the hexagonal P6/mmm space group. The structure consists of one 7440-42-8 atom inside a Ta2N3 framework. In the Ta2N3 framework, Ta(1) is bonded to six equivalent N(1) atoms to form a mixture of distorted corner, edge, and face-sharing TaN6 pentagonal pyramids. N(1) is bonded in a square co-planar geometry to four equivalent Ta(1) atoms. is represented by the CIF card [CIF]
