ThNi2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. Th(1) is bonded to twelve equivalent Ni(1) atoms to form a mixture of face and edge-sharing ThNi12 cuboctahedra. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Th(1) and three equivalent Ni(1) atoms.
