The IR-ATR and IR transmittance spectra of(4-O-acetyl ferula-to)triphenyltin(IV) and (fenoprofenato)tributyltin(IV)1 were recorded and analyzed. It was possible using the splitting of the (COO) band in the IR spectrum of the com-pounds to prove amonodentate binding mode of the carboxylate group to the Sn at-om. Also, the IR-ATR spectrum of theMCM-41 and SBA-15 mesoporous silica nano-particles (MSNs)2 were recorded and analyzed in order to check the mesoporous struc-ture of the synthesized materials. The changes of the band profile, assigned to the Si-OH(H2O) stretching vibration of the non-bridging oxygen atoms on heating the sam-ples, prove that the two MSNs are mesoporous. Finally, the organotin (IV) com-pounds immobilized in both MSNs were analyzed using IR-ATR and IR transmit-tance spectroscopy, in order to assess the loading intothe MSNs and the changes in their spectra connected to the interaction with the silica matrix.
