In the forty-fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Sr2+ and two Si4+ atoms. In the forty-sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one Si4+ atom. In the forty-seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one Si4+ atom. In the forty-eighth O2- site, O2- is bonded in a 2-coordinate geometry to two Sr2+, one Al3+, and one Si4+ atom.},
