L ligands can be stabilized by use of a bis-N-heterocyclic carbene
as an auxiliary cis-protecting ligand, while use
of more common protecting chelating ligands such as ethylenediamine
saw a Pd3L2 to Pd6L8 rearrangement
occur in solution. The crystalline Pd3L2 complexes
act as sponges, taking up 1,2-dichorobenzene or iodine in a single-crystal-to-single-crystal
fashion despite not exhibiting conventional porosity.
