Materials Data on BaSr4Cl10 by Materials Project
BaSr4Cl10 is Fluorite-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a body-centered cubic geometry to eight equivalent Cl1- atoms. All Ba–Cl bond lengths are 3.15 Å. There are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a body-centered cubic geometry to eight Cl1- atoms. There are four shorter (3.06 Å) and four longer (3.07 Å) Sr–Cl bond lengths. In the second Sr2+ site, Sr2+ is bonded in a body-centered cubic geometry to eight Cl1- atoms. There are four shorter (3.07 Å) and four longer (3.08 Å) Sr–Cl bond lengths. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded to two equivalent Ba2+ and two equivalent Sr2+ atoms to form a mixture of corner and edge-sharing ClBa2Sr2 tetrahedra. In the second Cl1- site, Cl1- is bonded to four equivalent Sr2+ atoms to form a mixture of corner and edge-sharing ClSr4 tetrahedra. In the third Cl1- site, Cl1- is bonded to four Sr2+ atoms to form a mixture of corner and edge-sharing ClSr4 tetrahedra.
