Crystal Structure and Catalytic Property of an Oxidomolybdenum(VI) Complex Derived from N′-(2-Hydroxy-3,5-Di-Tert-Butylbenzylidene)-4-Methylbenzohydrazide

详细

With a tridentate Schiff base ligand N′-(2-hydroxy-3,5-di-tert-butylbenzylidene)-4-methylbenzohydrazide (H₂L) and MoO₂(acac)₂, an oxidomolybdenum(VI) complex is prepared and characterized by elemental analysis, IR spectroscopy and X-ray structure determination. The complex crystallizes in the monoclinic space group C2/c with unit cell dimensions a = 20.187(2) Å, b = 7.9094(8) Å, c = 33.233(3) Å, β = 97.394(2)°, V = 5262.1(9) ų, Z = 8, R₁ = 0.0491, and wR₂ = 0.1322. The single crystal X-ray diffraction analysis reveals that the Mo atom is coordinated by NOO donor atoms of the Schiff base ligand, the methanol O atom, and two oxo groups in an octahedral coordination. Catalytic oxidation of the complex on some olefins is performed.
