title: Exopolyhedral ligand flipping on isomerisation of novel supraicosahedral stannacarboranes.
abstract: Novel p-block metallacarboranes with 4,1,10-SnC2B10 and 4,1,12-SnC2B10 architectures are described; the structures of bipyridyl adducts of these compounds reveal very different bipyridyl orientations yielding unique experimental information on the relative trans influences of facial B and C atoms in the cage.
