A series of α-aminophosphonates bearing the ferrocenyl moiety were obtained by the addition of diethyl phosphite to an azomethine bond of Schiff bases. The compounds were characterized by elemental analysis, IR, 1H NMR and 31P NMR spectra. X-ray crystallography of 3h reveals that it belongs to triclinic system P-1 space group, with a＝0.9728 nm, b＝1.1056 nm, c＝1.3713 nm, α＝108.445(2)°, β＝98.649(2)°, γ＝104.890(2)°, final R＝0.049, wR＝0.1152.

Key words: α-aminophosphonate, ferrocene, synthesis, crystal structure, chiral
