Synthesis, Characterization and Biological Activity of Cis- Dioxomolybdenum(VI) Schiff base Complex [MoO2(L)2]

A new dioxo-molybdenum(VI) complex [MoO2(L)2] was synthesized using 2,4-dihydroxy–benzalmethylene-o,o’- diethylphosphorohydrazonothionate (HL) as bidentate ON donor Schiff base ligand and MoO2(acac)2. This new compound was characterized by elemental analysis, IR, 1HNMR, MS, UV/vis, and molar conductivity, and the six- coordinate structure with [cis-MoO2]2+ group in the complex was proposed on the basis of spectroscopic characterization. The insecticidal activity of the Mo(VI) complex to bollworm was investigated, and its effect on the cell survial rate of mung bean sprouts was also discussed. The results showed that the activities of the complex in killing aphid were more effective than that of methamidophos and lower in killing red spider than that of methamidophos. Moreover, the complex could promote the cell survial rate of mung bean sprouts.
