The structure described by Na10YbSn12 crystallizes in the cubic I-43m space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to four equivalent Sn(1) atoms to form corner-sharing NaSn4 tetrahedra. In the second Na site, Na(2) is bonded in a 9-coordinate geometry to one Yb(1) and nine equivalent Sn(1) atoms. Yb(1) is bonded in a 16-coordinate geometry to four equivalent Na(2) and twelve equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to two equivalent Na(1), three equivalent Na(2), one Yb(1), and three equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
