Several new peroxo complexes of molybdenum(VI), uranium(VI), zirconium(IV) and thorium(IV) containing some bidentate amino acids have been synthesized and characterized. The complexes have the general formulae [M(O)(O<sub>2</sub>)L<img src='http://www.niscair.res.in/jinfo/two.gif' border=0>] and [M'(O<sub>2</sub>)L<img src='http://www.niscair.res.in/jinfo/two.gif' border=0>, [MO(O)(O<sub>2</sub>)L’<sup>2-</sup>H<sub>2</sub>O and [M’(O<sub>2</sub>)L’<sup>2-</sup>H<sub>2</sub>O][M=Mo(VI) and U(VI); M'=Zr(IV) and Th(IV); L<sup>-</sup> = glycinate, leucinate: L’<sup>2-</sup> = tyrosinate]. The complexes react with trans-stilbene, PPh<sub>3</sub>, and AsPh<sub>3</sub> giving their oxides. The IR spectra of the complexes indicate that the frequency of the <em>v</em><sub>1</sub>-mode of the M(O<sub>2</sub>) grouping. which is essentially an O - O stretch decrease with an increase in the atomic number of metal in a group. |
