The structure described by Hf2TaN3 crystallizes in the hexagonal P6/mmm space group. Hf(1) is bonded to six equivalent N(1) atoms to form a mixture of distorted corner, face, and edge-sharing HfN6 pentagonal pyramids. Ta(1) is bonded in a hexagonal planar geometry to six equivalent N(1) atoms. N(1) is bonded to four equivalent Hf(1) and two equivalent Ta(1) atoms to form a mixture of corner, face, and edge-sharing NHf4Ta2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. is represented by the CIF file [CIF]
