| Abstract: | Complexes of Iron with Aromatic Ligands The reaction of FeCl3 · 6 H2O with several substituted o-phenylene diamines forms complexes of the Fe(II)-ion with o-quinone diimines. Before the formation of these complexes there are a few of redox reactions between Fe(III)ions and the diamines. The Fe(III)/o-quinone diimine-complex is an intermediate which was characterized by means of spectroscopic methods. The two forms of 6-oxy-7-nitrosobenzthiazoline produce only one 1:3 complex with Fe(II)ions. Also the N-methyl-6-oxy-7-nitrosobenzthiazolium iodide forms a 1:3 complex. In the former complex the quinone-oxim-form is the ligand. The isolated complexes were characterized through elemental analysis and physical methods. |
