Palladium complexes of unsymmetrical 1,3-bis(aryliminio)isoindoline (BAI) ligands: A novel class of complexes exhibiting unusual structural features

The metallation of two homologous, unsymmetrical BAI (1,3-bis(aryliminio)isoindoline) ligands with palladium acetate leads to square–planar cyclometallated PdII complexes, comprising a C–H bond activated dianionic and tetradentate BAI ligand. In the solid state these isostructural monomeric complexes form a structural motif containing large voids, despite the absence of other than dispersive intermolecular interactions.

A simple and efficient one-pot synthesis of unsymmetrical BAI ligands is reported. The C–H bond activated palladium(II) complexes of two tailor-made unsymmetrical BAI ligands form, in the solid state, a structure containing large voids, despite the absence of other than dispersive intermolecular interactions.Figure optionsDownload as PowerPoint slide
