Abstract

Two new multi-domain α-diimine ligands capable of tri-hydrogen-bonding interactions are described; the non-planar dicyclopalladated complex [Pd₂Br₂L] 3a (X = Br) has imposed chirality and contains a short non-bonded 1,6-N⋯N′ contact of 2.75 Å; the cationic (2a) form of the pseudo-terpyridine molecule 2 has a virtually planar central core and is shown to be a potential host material.
