The title compound was synthesized from La, LaCl{sub 3} and Co under Ar atmosphere at 800 deg. C. It crystallizes in space group P4{sub 2}/n (no. 86) with lattice constants a=11.308(2) A and c=14.441(3) A. The structure features an isolated Co-centered La{sub 6} octahedron with all corners and edges, and 2 of its 8 triangular faces coordinated by Cl atoms. The La{sub 6}Co octahedron is significantly distorted, and the La coordination by Cl atoms deviates from the common close-packing arrangements found in other reduced rare earth metal halides. Structure, bonding and physical properties of the compound have been investigated. - Graphical abstract: La{sub 6}Cl{sub 11}Co octahedron exhibiting a mixed M{sub 6}X{sub 12}/M{sub 6}X{sub 12} coordination environment.
