Abstract

A Au(i)-N-heterocyclic-carbene (NHC)-edged Pd₆L₁₂ molecular metal-organic cage is assembled from a Au(i)-NHC-based bipyridyl bent ligand and Pd²⁺. The octahedral cage structure is unambiguously established by NMR, electrospray ionization-mass spectrometry and single crystal X-ray crystallography. The electrochemical behaviour was analyzed by cyclic voltammetry. The octahedral cage has a central cavity for guest binding, and is capable of encapsulating PF₆ ^- and BF₄ ^- anions within the cavity.
