The structure described by Sr(AlPb)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a body-centered cubic geometry to eight equivalent Pb(1) atoms. Al(1) is bonded to four equivalent Pb(1) atoms to form a mixture of corner and edge-sharing AlPb4 tetrahedra. Pb(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
