In the sixteenth O2- site, O2- is bonded to three Sm+2.67+ and one Mo6+ atom to form distorted OSm3Mo tetrahedra that share corners with four OSm4 tetrahedra, edges with two OSm4 tetrahedra, and edges with two OSm3Mo trigonal pyramids. In the seventeenth O2- site, O2- is bonded in a 4-coordinate geometry to three Sm+2.67+ and one Mo6+ atom. In the eighteenth O2- site, O2- is bonded in a 4-coordinate geometry to three Sm+2.67+ and one Mo6+ atom. In the nineteenth O2- site, O2- is bonded to three Sm+2.67+ and one Mo6+ atom to form a mixture of distorted edge},
