New complexes derived from the reaction of Mo(NO)Tp

Cl2; Tp
= tris(3,5-dimethylpyrazolyl)
borate with a series of manganese(II) Schiff bases have been synthesized. Characterization by UV, IR, MS and
elemental analysis support their formulations. Cyclic and differential pulse voltammograms of manganese(II)
Schiff base monometallic complexes exhibit one reduction peak which may be associated with the reduction of
the manganese(II) center. In CH3CN solutions, the molybdenum(II)-manganese(II) bimetallic complexes showed
two reversible reduction peaks which are associated with the reduction of the molybdenum and manganese
centers. In CH2Cl2, only the reduction of molybdenum(II) center exhibited reversibility while the reduction of
manganese(II) center was irreversible. These observations demonstrate that reduction potentials for bimetallic
complexes are solvent dependent.
