Synthesis, Crystal Structure, and Catalytic Property of a Dioxomolybdenum(VI) Complex Derived from N'-(3-Bromo-5-Chloro-2-Hydroxybenzylidene)-4-Nitrobenzohydrazide

详细

New dioxomolybdenum(VI) complex [MoO₂(L)(CH₃OH)], where L is the dianionic form of N'- (3-bromo-5-chloro-2-hydroxybenzylidene)-4-nitrobenzohydrazide (H₂L), was prepared and characterized by IR and UV-Vis spectra, as well as single crystal X-ray diffraction (CIF file ССDС no. 1567063). The complex crystallizes as the monoclinic space group P2₁/c with unit cell dimensions a = 13.8471(10), b = 7.5618(6), c = 17.9445(12) Å, β = 90.107(2)°, V = 1878.9(2) ų, Z = 4, R¹ = 0.0821, wR₂ = 0.0907, GOOF = 1.024. X-ray analysis indicates that the complex is a dioxomolybdenum(VI) species with the Mo atom in octahedral coordination. The catalytic oxidation property of the complex with tert-butylhydroperoxide in CH₂Cl₂ was studied.
