摘要：

An amide-linked ferrocene dimer, [(CH3CONHC5H4)Fe(C5H4CONHC5H4)Fe(C5H4CONHCH3)] (7), and a monomer, [(CH3CONHC5H4)Fe(C5H4CONHCH3)] (5), were synthesized, and their unique structures were determined by X-ray analysis. Amide planes are stacked with respect to each other in both crystal and dilute solution. These complexes form intermolecular NH ... O=C hydrogen bonds in the crystal. On the other hand, they form intramolecular NH ... O=C hydrogen bonds in a dilute solution as established by IR and H-1 NMR measurements. Spectral data suggest the presence of flapping structures in solution. Crystal data for 5: triclinic, P (1) over bar, a = 9.358(3) Angstrom, b = 9.947(4) Angstrom, c = 7.946(3) Angstrom, alpha = 106.86(3)degrees, beta = 113.15(3)degrees, gamma = 76.59(3)degrees, V= 644.9(5) Angstrom(3), Z = 2.7(.1)/2EtCN: orthorhombic, Pna(1), a = 7.467(4) Angstrom, b = 14.048(4) Angstrom, c = 23.400(5) Angstrom, Z = 4.
