[{(H_2O)Ni(enMe)_2Mo_4~VMo_4~(VI)V_8~(IV)(V~VO_4)O_(40)}_2 {Ni(enMe)_2}] [Ni(enMe)_2]_4·8H_2O: The First Dimer of Polyoxometalates Linked through Coordination Fragment

摘要

The hydrothermal reaction of V_2O_5, MoO_3, NiCl_2·6H_2O, enMe (1,2-diaminopropane) and H_2O produces [{(H_2O)Ni(enMe)_2Mo_4~VMo_4~(VI)V_8~(IV)(V~VO_4)O_(40)}_2{Ni(enMe)_2}]-[Ni(enMe)_2]_4·8H_2O, which is the first compound containing polyanion dimer linked by transition metal coordination fragment. The structure of this compound was determined by single crystal X-ray diffraction, EPR and IR analysis.
