The crystal structure described by (Ta2N3)2F2 crystallizes in the hexagonal P6/mmm space group. The structure consists of one hydrofluoric acid 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 face, corner, and edge-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 file [CIF]
