HfNbMoAu crystallizes in the trigonal R3m space group. Hf(1) is bonded in a 10-coordinate geometry to three equivalent Nb(1), four equivalent Mo(1), and three equivalent Au(1) atoms. All Hf(1)-Nb(1) bond lengths are 2.70 Å. There are three shorter (2.72 Å) and one longer (3.51 Å) Hf(1)-Mo(1) bond length. All Hf(1)-Au(1) bond lengths are 2.70 Å. Nb(1) is bonded in a single-bond geometry to three equivalent Hf(1), one Mo(1), and four equivalent Au(1) atoms. The Nb(1)-Mo(1) bond length is 0.47 Å. There are three shorter (2.72 Å) and one longer (3.51 Å) Nb(1)-Au(1) bond length. Mo(1) is bonded in a single-bond geometry to four equivalent Hf(1), one Nb(1), and three equivalent Au(1) atoms. All Mo(1)-Au(1) bond lengths are 2.70 Å. Au(1) is bonded in a 10-coordinate geometry to three equivalent Hf(1), four equivalent Nb(1), and three equivalent Mo(1) atoms.
