K Li Li Be
KLi2Be crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KLi2Be clusters. K(1) is bonded in a 1-coordinate geometry to one Li(1) and one Be(1) atom. The K(1)-Li(1) bond length is 1.59 Å. The K(1)-Be(1) bond length is 1.68 Å. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 3-coordinate geometry to one K(1), one Li(2), and one Be(1) atom. The Li(1)-Li(2) bond length is 1.03 Å. The Li(1)-Be(1) bond length is 1.90 Å. In the second Li site, Li(2) is bonded in a distorted single-bond geometry to one Li(1) atom. Be(1) is bonded in a 2-coordinate geometry to one K(1) and one Li(1) atom.
