Abstract

Over 100 heterometallic FeCu complexes, from heterodi- to heteropolymeric have been included in this review. The complexes contain the FeCu, Fe₂Cu, FeCu₂, FeCuMo; Fe₃Cu, Fe₂Cu₂, Fe₂CuM (M=Hg or Co); Fe₄Cu, Fe₃CuTe; Fe₄Cu₂, Fe₃Cu₃; FeCu₆, FeCu₂Ru₄; Fe₄Cu₄, Fe₄Cu₅; Fe₆Cu₅ and {FeCu}_n metallic cores. The mean M-M bond distance elongated in the order: 2.520Å (Fe-Cu) < 2.638Å (Cu-Cu) < 2.663Å (Fe-Fe). The most common ligands for the iron atoms are C donors, and for copper atoms are O and N donors. There are several relationships between the M-L, M-L-M and L-M-L data, which are discussed and compared with those found in FeAu complexes.
