A trifluoromethyl substituted organoimido derivative of the hexametalate cluster: Synthesis, crystal structure and bioactivity of [Mo6O17(NAr)2]2− (Ar = o-CF3C6H4)

The hexamolybdate cluster has been functionalized with fluorine-containing aromatic amine by the DCC (N,N′-dicyclohexylcarbodiimide) dehydrating protocol and a novel bifunctionalized arylimido derivative of hexamolybdate bearing the electron-withdrawing trifluoromethyl group, (Bu4N)2[Mo6O17(NAr)2] (Ar = o-CF3C6H4), has been prepared. Complete assignments were achieved for the title compound by elemental analysis, IR, 1H NMR, UV/visible and single-crystal X-ray diffraction analyses. The preliminary agricultural biological activity test indicated that it has some herbicidal and insecticidal activities.
