Abstract
Three metal complexes with ferrocenecarboxylate ligands, [M2(η 2-FcCOO)2(μ2-η 2-FcCONHCH2COO)2(phen)2] · nH2O [M = Pb, n = 6 (1) and M = Cd, n = 2 (2)] and [Cd(FcCONHCH2COO)(μ2-FcCONHCH2COO)(2,2′-bipy)(H2O)] n (3) (FcCOOH = ferrocenemonocarboxylic acid, FcCONHCH2COOH = N-ferrocenylformylglycine, phen = 1,10-phenanthroline, 2,2′-biby = 2,2′-bipyridine), were synthesized and characterized by elemental analysis, IR, and single crystal X-ray diffraction analysis. Structural studies revealed that 1 and 2 have similar binuclear structures, but 3 exhibits a 1-D chain structure. The difference in the structures of ferrocenylcarboxylate-containing cadmium(II) complexes is due to steric hindrance of ferrocenyl groups.
