|Abstract:||The intercalation of bis-iminodiacetatochromium(III) ion, [Cr(ida)2]-, in the interlayer of ZnAl-layered double hydroxide (LDH) through rehydration of ZnAl(O) mixed oxide and its characterization by XRD, TG-DTA, FT-IR and UV-vis-DRS is described. X-ray diffraction studies reveal the increase of basal spacing in the ZnAl-LDH–Cr(ida) hybrid from 7.69 Å to 12.55 Å due to intercalation of [Cr(ida)2]-, which is also evident from FT-IR and UV-vis-DR spectra. Thermogravimetric analyses show a marginal increase in the decomposition temperature for the [Cr(ida)2]- moiety with exothermic peaks in the LDH–Cr(ida) hybrid, indicating enhanced thermal stability of the [Cr(ida)2]- ion in the LDH interlayer. This method may be useful for intercalation of other anionic Cr(III) complexes of biological importance.|
