A macrocycle containing a pair of bipyridine moieties with a linker designed using the computer program CAVEAT exhibits unique selectivity in the binding of zinc ion relative to other metals.
The heterobimetallic CpFe(μ-η5: η5-as-indacenediide)RhL2 complexes (L2 = COD (2), NBD (3), (ethylene)2 (4)) have been obtained from metalation of the mononuclear lithium CpFe(η5-as-indacenediide) with [Rh(μ-Cl)L2]2. Mixtures of syn and anti heterobimetallic complexes were formed and fully characterized by 2D NMR spectroscopy. The reactivity at the rhodium center is greatly influenced by the presence
