The material structure described by Hf2PdAl3 crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 16-coordinate geometry to four equivalent Hf(1), three equivalent Pd(1), and nine equivalent Al(1) atoms. Pd(1) is bonded to six equivalent Hf(1) and six equivalent Al(1) atoms to form a mixture of face and edge-sharing PdHf6Al6 cuboctahedra. Al(1) is bonded in a distorted water-like geometry to six equivalent Hf(1) and two equivalent Pd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
