Crystal structure and molecular geometry of 7,8-µ-dimethylalumina-1,2-dicarba-nido-undecaborane(13), B9C2H12AlMe2, at –100 °c

Abstract
The title compound, has been subjected to a low-temperature (–100 °C)X-ray diffraction study. The compound crystallizes in the non-centrosymmetric triclinic space group P1 (C1 1, No. 1) with a= 7·460(6), b= 6·462(7), c= 6·985(4)Å, α= 115·37(5), β= 97·02(11), γ= 87·61(10)°, Z= 1. The structure was solved from photographic data by Fourier methods and refined by least-squares techniques to R 13·5% for 875 non-zero reflections. All non-hydrogen atoms were located. The B9C2H12 moiety is present as an icosahedral fragment with the AlMe2 group lying outside the cage and interacting with only two boron atoms.
