In the first Sr2+ site, Sr2+ is bonded in a 5-coordinate geometry to five Cl1- atoms. There are a spread of Sr–Cl bond distances ranging from 2.90–2.99 Å. In the second Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven Cl1- atoms. There are a spread of Sr–Cl bond distances ranging from 2.96–3.20 Å. In the third Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven Cl1- atoms. There are a spread of Sr–Cl bond distances ranging from 2.93–3.19 Å. In the fourth Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven Cl1- atoms. There are a spread of Sr–Cl bond distances ranging from 2.93–3.53 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in an octahedral geometry to six Cl1- atoms. There are a spread of La–Cl bond distances ranging from 2.76–2.86 Å. In the second La3+ site, La3+ is bonded in a pentagonal pyramidal geometry to six Cl1- atoms. There are a spread of La–Cl bond distances ranging from 2.75–2.88 Å.
