The crystal and molecular structure of (s1,4´,2,1´)-3,3´-commo-bis [8-methoxy-1,2-dicarba-3-nickela-closo-dodecaborane (11)], [8-CH₃O-1,2-C₂B₉H_1O]₂Ni

[8-CH₃0-C₂B₉H₁₀]_2Ni is monoclinic, space group P2₁/b, with a =15.208(3), b =13.762(4), c = 10.363(1)Å, γ = 117.25(2)°, Z =4. The structure was solved using the heavy-atom method and refined by least-squares up to R = 0.066. The structure consists of two dicarbollide ligands coordinated by the π-pentagonal faces to the Ni atom. These ligands form a new staggered conformation (s-1, 4´,2, 1´) with cages distorted to each other by an angle of 112°.
