A novel ethylenediamine (En) based metal-organic frameworks (MOFs) of Cr-MOFs, En/MIL-100(Cr), with phosphorous acid tags was prepared. MIL-100(Cr)/NHEtN(CH2PO3H2)2 characterized by a variety of techniques, including fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), elemental mapping and energy dispersive X-ray (EDS), transmission electron microscopy (TEM), Thermal gravimetric (TG), differential thermal gravimetric (DTG). MIL-100(Cr)/NHEtN(CH2PO3H2)2 successfully used for the synthesis of spiro derivatives.
