K La La La
KLa3 crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one KLa3 cluster. K(1) is bonded in a distorted single-bond geometry to one La(1) and one La(3) atom. The K(1)-La(1) bond length is 0.98 Å. The K(1)-La(3) bond length is 3.54 Å. There are three inequivalent La sites. In the first La site, La(1) is bonded in a distorted single-bond geometry to one K(1) atom. In the second La site, La(2) is bonded in a 1-coordinate geometry to one La(3) atom. The La(2)-La(3) bond length is 1.26 Å. In the third La site, La(3) is bonded in a 2-coordinate geometry to one K(1) and one La(2) atom.
