The compound described by Na3YbCl6 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms to form NaCl6 octahedra that share corners with six equivalent Yb(1)Cl6 octahedra. The corner-sharing octahedral tilt angles range from 41-56°. In the second Na site, Na(2) is bonded in a 7-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), and three equivalent Cl(3) atoms. Yb(1) is bonded to two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms to form YbCl6 octahedra that share corners with six equivalent Na(1)Cl6 octahedra. The corner-sharing octahedral tilt angles range from 41-56°. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to one Na(1), two equivalent Na(2), and one Yb(1) atom to form distorted corner-sharing ClNa3Yb trigonal pyramids. In the second Cl site, Cl(2) is bonded in a see-saw-like geometry to one Na(1), two equivalent Na(2), and one Yb(1) atom. In the third Cl site, Cl(3) is bonded in a 3-coordinate geometry to one Na(1), three equivalent Na(2), and one Yb(1) atom. is represented by the CIF card [CIF]
