Half-rotation in a [2]catenane via interconvertible Pd(II) coordination modes
David A. Leigh, Paul J. Lusby, Alexandra M. Z. Slawin and D. Barney Walker
Reaction of a [2]catenane with Pd(OAc)2 binds both macrocycles to the metal, locking them in position; treatment with PdCl2, however, results in coordination of only one ring, producing a half-turn in the relative orientation of the [2]catenane components in both solution and the solid state.
