La(YSb)2 crystallizes in the monoclinic Cm space group. La(1) is bonded in a single-bond geometry to four equivalent Y(1) and one Sb(1) atom. There are two shorter (3.17 Å) and two longer (3.44 Å) La(1)-Y(1) bond lengths. The La(1)-Sb(1) bond length is 1.89 Å. Y(1) is bonded in a 6-coordinate geometry to two equivalent La(1), three equivalent Y(1), and one Sb(2) atom. There is one shorter (1.96 Å) and two longer (3.50 Å) Y(1)-Y(1) bond lengths. The Y(1)-Sb(2) bond length is 2.94 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a linear geometry to one La(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 0.53 Å. In the second Sb site, Sb(2) is bonded in a 3-coordinate geometry to two equivalent Y(1) and one Sb(1) atom.
