Templating metallocycles with a macrocycle: synthesis, structures and magnetic studies of {Cr₁₁M₂} complexes.

ABSTRACT: Addition of 1,4,8,11-tetrazacyclotetradecane (cyclam) to a reaction that produces octametallic rings when simpler amines are used, produces {Cr₁₁M₂} "pretzels" (M = Zn^II or Cu^II) where the cyclam coordinates to the M^II ion which then sits at the centre of a twelve-metal macrocycle. Magnetic studies were fitted using the finite-temperature Lanczos method (FTLM), and the results demonstrate that exchange interactions are transferable from previous exchange-coupled Cr^III rings.
