Crystal structures of the carborane dianions [1,4-(PhCB₁₀H₁₀C)₂C₆H₄]²⁻ and [1,4-(PhCB₁₀H₁₀C)₂C₆F₄]²⁻ and the stabilizing role of the para-phenylene unit on 2n+3 skeletal electron clusters.

Kahlert J, Stammler HG, Neumann B, Harder RA, Weber L, Fox MA - Angew. Chem. Int. Ed. Engl. (2014)

Bottom Line: While carboranes with 2 n+2 and 2 n+4 (n=number of skeletal atoms) skeletal electrons (SE) are widely known, little has been reported on carboranes with odd SE numbers.The salts of the dianions were isolated by reduction with sodium metal and their unusual structures were determined by X-ray crystallography.The diamagnetic dianions contain two 2 n+3 SE clusters where each cluster has a notably long carborane C-carborane C distance of ca 2.4 Å.
