In the first Sr2+ site, Sr2+ is bonded in a 2-coordinate geometry to one Mg2+, one Mo6+, and twelve O2- atoms. The Sr–Mg bond length is 2.02 Å. The Sr–Mo bond length is 2.04 Å. There are a spread of Sr–O bond distances ranging from 2.74–2.92 Å. In the second Sr2+ site, Sr2+ is bonded in a 2-coordinate geometry to one Mg2+, one Mo6+, and twelve O2- atoms. The Sr–Mg bond length is 2.00 Å. The Sr–Mo bond length is 2.03 Å. There are a spread of Sr–O bond distances ranging from 2.74–2.99 Å. In the third Sr2+ site, Sr2+ is bonded in a 2-coordinate geometry to one Mo6+, one Fe2+, and four O2- atoms. The Sr–Mo bond length is 2.01 Å. The Sr–Fe bond length is 2.02 Å. There are a spread of Sr–O bond distances ranging from 2.72–2.87 Å. In the fourth Sr2+ site, Sr2+ is bonded in a 6-coordinate geometry to one Mg2+, one Mo6+, and four O2- atoms.
