The structure described by SmPd2Al3 crystallizes in the hexagonal P6/mmm space group. Sm(1) is bonded in a distorted hexagonal planar geometry to six equivalent Pd(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to four equivalent Pd(1) atoms. is represented by the CIF card [CIF]
