The material structure described by Mg8Yb19 is Tungsten structured and crystallizes in the cubic Im-3 space group. The structure is zero-dimensional and consists of two Mg8Yb19 clusters. Mg(1) is bonded in a 7-coordinate geometry to one Yb(3), three equivalent Yb(1), and three equivalent Yb(2) atoms. There are three inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 2-coordinate geometry to two equivalent Mg(1) atoms. In the second Yb site, Yb(3) is bonded in a body-centered cubic geometry to eight equivalent Mg(1) atoms. In the third Yb site, Yb(2) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms. is represented by the CIF file [CIF]
