Abstract
The stirring of [ortho-(HCC)-C5H4N] with [nido-B10H14] in
C)-C5H4N}2-arachno-B10H12] 1 in 93% yield. In the solid state, 1 has an extended complex three-dimensional structure involving intramolecular
CH)-C5H4N)-exo-9N-(ortho-(HC
C)-C5H4N)-arachno-B10H11] 6. An improved solvent-free route to 2 is also presented. This set of compounds features an increasing
C)-C5H4N], which gives [µ-1C,2B-[ortho-C5H4N-CH2]-closo-1-CB11H10] 7 (40%) in which one
C)-C5H4N] affords [NnBu4][7-(ortho-N
C-C5H4N)-nido-B11H12], 8 (68%) and stirring [ortho-(N
C)-C5H4N] with [nido-B10H14] quantitatively affords the
C)-C5H4N}2-arachno-B10H12] 9. All compounds were characterised by
