The structure described by TaB2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. Ta(1) is bonded to twelve equivalent B(1) atoms to form a mixture of edge and face-sharing TaB12 cuboctahedra. B(1) is bonded in a 9-coordinate geometry to six equivalent Ta(1) and three equivalent B(1) atoms. is represented by the CIF file [CIF]
