Abstract

Two new dioxomolybdenum(VI) complexes, [MoO2L(EtOH)] (I) and [MoO2L(Sal)] (II), where L is the dianionic form of 4-chloro-2-{[4-(diethylamino)-2-hydroxybenzylidene]amino}phenol (H2L), Sal is 4-diethylaminosalicylaldehyde, were prepared and characterized by IR and UV-Vis spectra, as well as single crystal X-ray diffraction (CIF files CCDC nos. 1849408 (I) and 1849409 (II)). Complex I crystallizes as the triclinic space group \(P\bar {1}\) with unit cell dimensions a = 7.3050(10), b = 11.6969(16), c = 13.3433(19) Å, α = 103.915(2)°, β = 102.542(2)°, γ = 105.676(2)°, V = 1015.8(2) Å3, Z = 2, R1 = 0.0616, wR2 = 0.1579, GOOF = 1.080. Complex II crystallizes as the triclinic space group \(P\bar {1}\) with unit cell dimensions a = 7.0773(11), b = 12.8817(12), c = 16.420(2) Å, α = 107.000(2)°, β = 101.478(2)°, γ = 91.416(2)°, V = 1397.4(3) Å3, Z = 2, R1 = 0.0484, wR2 = 0.1048, GOOF = 1.015. X-ray analyses indicate that the complexes are dioxomolybdenum(VI) species with the Mo atoms in octahedral coordination. The catalytic oxidation property of the complexes with tert-butylhydroperoxide in CH2Cl2 was studied.
