“…In complexes Fe-SHA, Fe-5CSHA and Fe-3,5DCSHA the salicylhydroxamic moiety (SHA) is a potentially tridentate. The three groups, namely phenolic, carbonyl and hydroxamic function (-N-OH) are involved in the coordination as indicated by stoichiometric composition, IR and visible spectra [3,4]. The effect of substitution in the benzene nucleus on the isomer shift is found to be very small.…”

“…Fe-3,5 di chloro salicylhydroxamate(Fe-3,5DCSHA) along with Fe-benzohydroxamate (Fe-BHA) for comparison. One of the aims of the present investigation is to resolve the controversy regarding the participation of phenolic -OH group of salicylhydroxamic acids in chelation favouring our recent results derived from vibrational spectra and X-ray K-absorption studies [4,5].…”

Polymeric complexes of iron (II) salicylhydroxamic acids: Fe‐SHA, Fe‐5CSHA, Fe‐3,5DCSHA along with Fe‐BHA, where SHA = salicylhydroxamic acid, 5CSHA = ‐5‐chloro salicylhydroxamic acid, 3,5DCSHA = 3,5 di‐chloro salicylhydroxamic acid and BHA = Benzohydroxamic acid, have been prepared, characterized by elemental and spectral analysis and identified by the electronic spectra as ML2.2H2O, where L stands for the salicylhydroxamic acid moiety and M stands for Fe(II). Various Mössbauer parameters obtained at room temperature, change with respect to the kinds of chelating agent which may be attributed to the effect of substitution in the salicylhydroxamic acid moiety. Quadrupole splitting and isomer shift values have been explained in terms of restricted rotation between C6H5‐°C‐ bond due to the π‐electron system in the benzene nucleus.
