The structure described by ScPb3 crystallizes in the tetragonal I4/mmm space group. Sc(1) is bonded to four equivalent Pb(2) and eight equivalent Pb(1) atoms to form a mixture of edge, face, and corner-sharing ScPb12 cuboctahedra. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 8-coordinate geometry to four equivalent Sc(1) and four equivalent Pb(1) atoms. In the second Pb site, Pb(2) is bonded in a square co-planar geometry to four equivalent Sc(1) atoms. is represented by the CIF file [CIF]
