The structure described by TiTa2N3 crystallizes in the hexagonal P6/mmm space group. Ti(1) is bonded in a hexagonal planar geometry to six equivalent N(1) atoms. Ta(1) is bonded to six equivalent N(1) atoms to form a mixture of distorted edge, face, and corner-sharing TaN6 pentagonal pyramids. N(1) is bonded to two equivalent Ti(1) and four equivalent Ta(1) atoms to form a mixture of edge, face, and corner-sharing NTa4Ti2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. is represented by the Crystallographic Information File (CIF) [CIF]
