K K La W
K2LaW crystallizes in the triclinic P1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to two equivalent K(1), one La(1), and one W(1) atom. Both K(1)-K(1) bond lengths are 3.37 Å. The K(1)-La(1) bond length is 3.59 Å. The K(1)-W(1) bond length is 4.15 Å. In the second K site, K(2) is bonded in a 2-coordinate geometry to two equivalent La(1) and one W(1) atom. There is one shorter (1.89 Å) and one longer (2.86 Å) K(2)-La(1) bond length. The K(2)-W(1) bond length is 4.15 Å. La(1) is bonded in a 1-coordinate geometry to one K(1), two equivalent K(2), and one W(1) atom. The La(1)-W(1) bond length is 3.77 Å. W(1) is bonded in a 5-coordinate geometry to one K(1), one K(2), one La(1), and two equivalent W(1) atoms. Both W(1)-W(1) bond lengths are 3.37 Å.
