Abstract

original image

The use of two tridentate ligands is the secret of success for the self-assembly of structurally intriguing tetranuclear CoII complexes. The cation [Co4(L)4]8+ (1) exists as a [2 × 2]-grid of octahedrally coordinated metal ions located at the corners of a square. The complex displays multiple redox processes and is of potential redox processes and is of potential interest for the development of electrochemically addressable inorganic arrays (R1, R2 = H, Me; • = CoII).
