Abstract. A new polyoxometalates with Keggin structure, [Fe(phen)3]2[GeMO^Ⅵ 8Mo^Ⅴ 4O40]·0.5H2O has been hydrothermally synthesized by using pre-synthesized H4 [GeMo12O40]·xH2O as building block. It crystallizes in the triclinic system, space group P1, a = 1. 216 0(2) nm, b = 1. 367 6(3) nm, c = 1. 462 7(3) nm,α = 105.05(3)°,β= 109.64(3)°, γ=93.07(3)°, V=2. 185 6(7) nm^3,Z = 2, F(000) = 147 6,R = 0. 068 8, ωR^2 = 0. 187 5. The compound was used as a bulk-modifier to fabricate a chemically modified carbon paste electrode (CPE) by direct mixing. Its electrochemical behavior was studied at the same time.
