Sr5Pb3F crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted square co-planar geometry to two equivalent Pb(1) and four equivalent Pb(2) atoms. In the second Sr site, Sr(2) is bonded in a single-bond geometry to two equivalent Pb(1), three equivalent Pb(2), and one F(1) atom. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 10-coordinate geometry to two equivalent Sr(1) and eight equivalent Sr(2) atoms. In the second Pb site, Pb(2) is bonded in a 9-coordinate geometry to two equivalent Sr(1), six equivalent Sr(2), and one Pb(2) atom. F(1) is bonded in a tetrahedral geometry to four equivalent Sr(2) atoms.
Sr5Pb3F crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted square co-planar geometry to two equivalent Pb(1) and four equivalent Pb(2) atoms. Both Sr(1)-Pb(1) bond lengths are 4.02 Å. All Sr(1)-Pb(2) bond lengths are 3.43 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to two equivalent Pb(1), three equivalent Pb(2), and one F(1) atom. Both Sr(2)-Pb(1) bond lengths are 3.63 Å. There are two shorter (3.50 Å) and one longer (3.60 Å) Sr(2)-Pb(2) bond length. The Sr(2)-F(1) bond length is 2.52 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 10-coordinate geometry to two equivalent Sr(1) and eight equivalent Sr(2) atoms. In the second Pb site, Pb(2) is bonded in a 9-coordinate geometry to two equivalent Sr(1), six equivalent Sr(2), and one Pb(2) atom. The Pb(2)-Pb(2) bond length is 3.11 Å. F(1) is bonded in a tetrahedral geometry to four equivalent Sr(2) atoms.
