The structure described by ThNi2Al3 crystallizes in the hexagonal P6/mmm space group. Th(1) is bonded in a distorted hexagonal planar geometry to six equivalent Ni(1) and twelve equivalent Al(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Th(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to four equivalent Th(1) and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
