Abstract:
Characterization of heterobinuclear complexes containing molybdenum(II) nitrosyl metal fragment, Mo(NO)Tp

= tris(3,5-dimethylpyrazolyl) borate linked to p-functionalized Fe(Salen)Cl; by IR, UV, MS and elemental
analysis is herein described. The electrochemical behavior, investigated by both cyclic and differential pulse
voltammetry, indicates that the monometallic Fe(Salen)Cl complexes exhibit one reduction peak which may be
associated with the reduction of iron center while the heterobinuclear molybdenum-iron complexes exhibit two
reduction peaks which may be associated with the reduction of both molybdenum and iron centers. The reduction
potential of iron is more cathodic in Fe(Salen)Cl than in the binuclear complex showing that the electron deficient
molybdenum nitrosyl center modestly influences its reduction potential.
