Pm3Au is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Pm sites. In the first Pm site, Pm(1) is bonded to four equivalent Au(1) atoms to form a mixture of distorted edge and corner-sharing PmAu4 cuboctahedra. In the second Pm site, Pm(2) is bonded in a square co-planar geometry to four equivalent Au(1) atoms. Au(1) is bonded to four equivalent Pm(2) and eight equivalent Pm(1) atoms to form a mixture of edge, face, and corner-sharing AuPm12 cuboctahedra.

In the first Pm site, Pm(1) is bonded to four equivalent Au(1) atoms to form a mixture of distorted edge and corner-sharing PmAu4 cuboctahedra. All Pm(1)-Au(1) bond lengths are 3.47 Å. In the second Pm site, Pm(2) is bonded in a square co-planar geometry to four equivalent Au(1) atoms. All Pm(2)-Au(1) bond lengths are 3.33 Å. Au(1) is bonded to four equivalent Pm(2) and eight equivalent Pm(1) atoms to form a mixture of edge, face, and corner-sharing AuPm12 cuboctahedra.
