Abstract
Schiff-based ligands are good building blocks for iron complexes. In this work, a new mononuclear iron(III) complex based on hexadentate Schiff-based ligand with formula [Fe(3,2,3-sal2tet)]psca (3,2,3-sal2tet = N, N’, N’’, N’’’-1,5,8,12-tetraazadodecane-bis(salicylaldiminato), psca = p-sulfocinnamic acid) was prepared by subcomponent self-assembly method. A photo-responsive anion, psca, was incorporated into this system to study the effect of light-induced photo-isomerization of the anion on the spin state. 57Fe Mössbauer spectroscopy was employed to study the spin state of the precursor Fe(II) salt ([Fe(H2O)6]psca)2·2H2O and the resulting iron(III) complex.
