Abstract
A hexagonal molecular “palladawheel” consisting of six N,N’-diphenyl-2,6-pyridinedicarboxamide–Pd(II) pincer complexes held together via six Pd⋯OCAmide bonds was efficiently synthesized and crystallographically characterized. The hexameric ring possesses C3 (pseudo-S6) symmetry with up-down alternating phenyl substituents acting as interior “spokes” and exterior “propellers.”
