Li2YAl crystallizes in the orthorhombic Immm space group. Li(1) is bonded in a distorted single-bond geometry to one Y(1) and one Al(1) atom. Y(1) is bonded in a 6-coordinate geometry to two equivalent Li(1) and four equivalent Al(1) atoms. Al(1) is bonded to two equivalent Li(1) and four equivalent Y(1) atoms to form a mixture of distorted corner and edge-sharing AlLi2Y4 octahedra. The corner-sharing octahedra are not tilted.
Li2YAl crystallizes in the orthorhombic Immm space group. Li(1) is bonded in a distorted single-bond geometry to one Y(1) and one Al(1) atom. The Li(1)-Y(1) bond length is 3.34 Å. The Li(1)-Al(1) bond length is 2.63 Å. Y(1) is bonded in a 6-coordinate geometry to two equivalent Li(1) and four equivalent Al(1) atoms. All Y(1)-Al(1) bond lengths are 3.01 Å. Al(1) is bonded to two equivalent Li(1) and four equivalent Y(1) atoms to form a mixture of distorted corner and edge-sharing AlLi2Y4 octahedra. The corner-sharing octahedra are not tilted.
