La Al W W
LaW2Al is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaW2Al clusters. La(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms. Both La(1)-W(1) bond lengths are 1.39 Å. W(1) is bonded in a distorted L-shaped geometry to one La(1) and one Al(1) atom. The W(1)-Al(1) bond length is 1.39 Å. Al(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms.
