- A new cyclic molecule incorporating [Moᴵᴵᴵ(CN)₇]⁴⁻ has been characterized by single crystal X-ray methods, SQUID magnetometry and theoretical calculations. The wheel molecule [Moᴵᴵᴵ(CN)₇]₆[Ni(L)]₁₂(H₂O)₆ exhibits ferromagnetic Mo–Ni coupling which did not exist for the previously reported octacyanometallate analogue [Moᴵⱽ(CN)₈]₆[Ni(L)]₁₂(H₂O)₆. These results indicate that known supramolecular architectures incorporating octacyanometallates can be used as platforms for making new molecules incorporating seven-coordinate cyanide precursors.
