| 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. |
