Np2AuIn crystallizes in the trigonal R3m space group. There are two inequivalent Np sites. In the first Np site, Np(1) is bonded in a distorted linear geometry to one Au(1) and one In(1) atom. The Np(1)-Au(1) bond length is 2.15 Å. The Np(1)-In(1) bond length is 2.15 Å. In the second Np site, Np(2) is bonded in a single-bond geometry to one Au(1) atom. The Np(2)-Au(1) bond length is 2.15 Å. Au(1) is bonded in a distorted linear geometry to one Np(1), one Np(2), and three equivalent In(1) atoms. All Au(1)-In(1) bond lengths are 2.99 Å. In(1) is bonded in a 4-coordinate geometry to one Np(1) and three equivalent Au(1) atoms.
