A homologous series of electronically tuned 2,2',2''-nitrilotris(N-arylacetamide) pre-ligands (H L ) were prepared (R = NO , CN, CF , F, Cl, Br, Et, Me, H, OMe, NMe ) and some of their corresponding Fe and Zn species synthesized. The iron complexes react rapidly with O , the final products of which are diferric mu-oxo bridged species. The crystal structure of the oxidized product obtained from DMA solutions contain a structural motif found in some diiron proteins.
