PuIn crystallizes in the monoclinic C2/m space group. Pu(1) is bonded to six equivalent Pu(1) and six equivalent In(1) atoms to form a mixture of distorted corner, edge, and face-sharing PuPu6In6 cuboctahedra. In(1) is bonded in a 12-coordinate geometry to six equivalent Pu(1) and six equivalent In(1) atoms.
