The reaction of polyoxometalate anion [GeW11O39](8-) with the complex anion [(Mo2O4)-O-V(H2O)(2)(ox)(2)](2-) in the presence of CuCl2 center dot 2H(2)O and DMF (DMF = N,N-dimethyl formamide) at 85 degrees C in aqueous solution produces both a two-dimensional heteropoly blue H-2[alpha-(GeW10Mo2O40)-O-V][Cu(DMF)(3)H2O](2)center dot 5H(2)O (1) and a three-dimensional heteropoly blue H-4[alpha-(GeW10Mo2O40)-O-V](2) [CuK2(DMF)(6)] [K-4(DMF)(6)] (2), which demonstrates that different molar ratio of W : Cu in the reaction could conduct different multidimensional structures of 2D and 3D. The magnetic investigation of the two compounds in temperature range from 300 K to 2 K indicated the presence of strong antiferromagnetic interactions related with the two Mo-V ions in these two compounds.
