Open clamshell dinuclear palladium(ii) complexes possessing out-of-plane anisotropy

Abstract

Double cyclometalation of planar, oligomeric phenylpyridines yielded dinuclear palladium(II) complexes with novel out-of-plane anisotropy. An X-ray crystal structure analysis revealed that the complexes exhibit concave–convex geometry, and ¹H NMR measurement evidenced the occurrence of stable out-of-plane anisotropy. The dipole moment and Pd–Pd interaction were investigated by theoretical calculations.
