Synthesis of [Li(THF)(4)](2)[Th(eta(5)-C2B9H11)(2)X-2] (X=Cl, Br, I): The first dicarbollide complexes of thorium
The first thorium complexes incorporating dicarbollide ligands, [Li(THF)(4)](2)[Th(eta(5)-C2B9H11)(2)X-2] (X=Cl, Br, I) and [Li(THF)(4)][Th(eta(5)-C2B9H11)Br-3(THF)], have been prepared and characterized by a combination of spectroscopic and analytical techniques, The molecular structure of the dibromo derivative has been determined by single-crystal X-ray diffraction. [Li(THF)(4)](2)[Th(eta(5)-C2B9H11)(2)Br-2] is monoclinic, Cc (No, 9), a=26.303 (2) Angstrom, b=11.143 (2) Angstrom, c=20.054 (2) Angstrom, beta=103.263 (7)degrees, Z=4.
