Incorporation of [Fe(bipy)Cl4][bipy.H] (1) (where bipy is 2,2′-bipyridine) in the molecular
sieves of the type LTA, NaY and mesoporous Al-MCM-41 by using a “ship in a bottle
synthesis” approach was investigated. [Fe(bipy)Cl4][bipy.H] was successfullyincorporated in
the channels ofmesoporousAl-MCM-41, and the product was characterized by X-ray diffraction, FTIR and BET analysis. It was found that size criteria prevented the complex to be incorporated in smaller cages of the LTA or NaY zeolites.Incorporation of the complex into the channels of Al-MCM-41, on the other hand,did not affected morphology of the host as it is evident from SEM micrographs.
