摘要

以芳香腙配体N′-(2-羟基-3-甲氧基苄基)-3-甲基苯并肼(H2L1)和4-氟-N′-(2-羟基苄基)苯并肼(H2L2)为原料，室温下在乙醇中制备了两个新的二氧化钼(VI)配合物[MoO2L1(EtOH)](1)和[MoO2L2(EtOH)](2)。通过元素分析、红外光谱、紫外-可见光谱以及单晶x射线测定对两种配合物进行了表征。配合物中的Mo原子呈八面体配位。氢键稳定了配合物的晶体结构。研究了这两种配合物对苯乙烯环氧化反应的催化性能。

Ethanol-Coordinated Dioxidomolybdenum(VI) Complexes with Aroylhyrazone Ligands: Synthesis, Spectroscopic Characterization, Crystal structures and Catalytic Oxidation Property

Two new dioxidomolybdenum(VI) complexes, [MoO2L1(EtOH)] (1) and [MoO2L2(EtOH)] (2), derived from the aroylhydrazone ligands N’-(2-hydroxyl-3-methoxybenzylidene)-3-methylbenzohydrazide (H2L1) and 4-fluoro-N’-(2-hydroxylbenzylidene) benzohydrazide (H2L2), respectively, were prepared in ethanol under ambient temperature. Both complexes were characterized by elemental analysis, IR and UV-Vis spectroscopy, as well as single crystal X-ray determination. The Mo atoms in the complexes are in octahedral coordination. Crystal structures of the complexes are stabilized by hydrogen bonds. The catalytic property for epoxidation of styrene by both complexes was studied.
