The material described by Hf2AuAl3 crystallizes in the trigonal R-3m space group. Hf(1) is bonded in a 16-coordinate geometry to four equivalent Hf(1), three equivalent Au(1), and nine equivalent Al(1) atoms. Au(1) is bonded to six equivalent Hf(1) and six equivalent Al(1) atoms to form a mixture of corner and edge-sharing AuHf6Al6 cuboctahedra. Al(1) is bonded in a distorted linear geometry to six equivalent Hf(1) and two equivalent Au(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
