摘　　要：The novel amino acid containing polyoxometalate K 6[Cu(Ala) 2(H 2O) 2] 2[Cu 4(H 2O) 2\5(AsW 9O 34 ) 2]·16H 2O was synthesized from the reaction of K 10 [Cu 4(H 2O) 2(AsW 9O 34 ) 2]·20H 2O with β alanine. Its structure has been determined by single crystal X ray diffraction. It crystallizes in the triclinic space group P1 , with a =1.196 3(2) nm, b =1.536 5(3) nm, c =1.591 4(3) nm, α=93.97(3)°, β=110.88(3)°, γ=101.07(3)°, V =2.651 8(9) nm 3 and Z =1. Least squares refinement of the structure leads to R and R w factors of 0.067 3 and 0.162 8, respectively. An unusual structural feature of the compound is that the polyanion [Cu 4(H 2O) 2(AsW 9O 34 ) 2] 10- is linked with the amino acid complex of Cu 2+ by a μ oxygen atom.The novel amino acid containing polyoxometalate K 6[Cu(Ala) 2(H 2O) 2] 2[Cu 4(H 2O) 2\5(AsW 9O 34 ) 2]·16H 2O was synthesized from the reaction of K 10 [Cu 4(H 2O) 2(AsW 9O 34 ) 2]·20H 2O with β alanine.
