Na2YbCdSb2 crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 3-coordinate geometry to two equivalent Cd(1), one Sb(1), and four equivalent Sb(2) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to two equivalent Cd(1), two equivalent Sb(1), and two equivalent Sb(2) atoms. Yb(1) is bonded in a 5-coordinate geometry to four equivalent Cd(1), one Sb(2), and four equivalent Sb(1) atoms. Cd(1) is bonded in a 12-coordinate geometry to two equivalent Na(1), two equivalent Na(2), four equivalent Yb(1), two equivalent Sb(1), and two equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to one Na(1), two equivalent Na(2), four equivalent Yb(1), and two equivalent Cd(1) atoms. In the second Sb site, Sb(2) is bonded in a 9-coordinate geometry to two equivalent Na(2), four equivalent Na(1), one Yb(1), and two equivalent Cd(1) atoms.
