As silatranes and its related compounds have specific structures and have been demonstrated to show a significent biological activity, eleven new C-methylsubstituted 1-ferroceneacyloxysilatranes were synthesized via the reaction of ferrocenecarboxylic acids and C-methysubstituted 1-ethoxysilatrans. They were characterized by means of IR, 1H NMR and elemental analysis. X-ray structure determination of compound 1 indicates the presence of N→Si bond with a bond length of 0.2113(4) nm. It belongs to monoclinic system, space group P2(1)/c with a=1.4050(16) nm, b=1.2758(14) nm, c=1.1196(12) nm, α=90°, β=108.598(18)°, γ=90°, Z=4.
