Materials Data on Sr(AlPb)2 by Materials Project
Sr(AlPb)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr is bonded in a body-centered cubic geometry to eight equivalent Pb atoms. All Sr–Pb bond lengths are 3.65 Å. Al is bonded to four equivalent Pb atoms to form a mixture of edge and corner-sharing AlPb4 tetrahedra. All Al–Pb bond lengths are 2.91 Å. Pb is bonded in a 9-coordinate geometry to four equivalent Sr and four equivalent Al atoms.
