Abstract: A new molybdenum-vanadium polyoxometalate [PⅤMoⅥ7MoⅤVⅣ8O44][Ni(Phen)2OH]4·3H2O(1) was prepared under hydrothermal conditions, and characterized by elemental analysis, IR and single crystal X-ray diffraction analysis. The title compound crystallized in a triclinic system, P-1 space group, a=1.51300(11) nm, b=1.74813(15) nm, c=2.58896(18) nm, α=72.842(4)°, β=89.240(5)°, γ=72.627(5)°, V=6.2233(8) nm3, Z=1, R1=0.0962, wR2=0.2572. Compound 1 is composed of a highly reduced tetra-capped pseudo-Keggin polyoxoanion supporting four transition metal complexes. There are many hydrogen bond among polyoxoanion and water molecules, which enable the formation of three dimensional supramolecular array.

Key words: molybvanudates, supramolecular, hydrothermal synthesis, magnetic properties
