摘要

The trans-[Fe(cyclam)(NO)Cl]Cl-2 complex was synthesized by the reaction of cis-[Fe(cyclam)Cl-2]Cl with NO gas. The X-ray structure of the complex showed that the [Fe-NO] moiety is linear, consistent with the NO+ character of the nitric oxide ligand. This suggestion was reinforced by the IR data, which showed the vNO at 1888 cm(-1). The cyclic voltammogram of the trans-[Fe(cyclam)(NO)Cl](2+) Complex presented three electrochemical processes at -0.70, 0.08 and 0.40 V versus Ag/AgCl. The first and last redox processes are centered at the NO ligand, whereas the second is characteristic of the generated aqua species, trans-[Fe(cyclam)Cl(H2O)](2+). Upon irradiation at 330 nm, pH 3.4, the title complex releases the NO moiety with the concomitant generation of the trans-[Fe(cyclam)(H2O)Cl](+) complex as suggested by electronic and IR spectroscopy as well as by cyclic voltammetry technique.
