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.
Highlights
The self-assembly of metal–organic cages (MOCs)[1,2,3] has been investigated for diverse potential applications, such as catalysis,[4] sensing,[5,6] molecular storage and sequestration,[7] drug delivery,[8] and so on
