Abstract: The novel amino-acid-containing polyoxometalate K6[Cu(Ala)2(H2O)2]2[Cu4(H2O)2·(AsW9O34 )2]·16H2Owas synthesized from the reaction of K10 [Cu4(H2O)2(AsW9O34 )2]·20H2Owith β--alanine. Its structure has been determined by single crystal X-ray diffraction. It crystallizes in the triclinic space group P1, with a=1.1963(2) nm, b=1.5365(3) nm, c=1.5914(3) nm, α=93.97(3)°, β-=110.88(3)°, γ=101.07(3)°, V=2.6518(9) nm3 and Z=1. Least squares refinement of the structure leads to Rand Rw factors of 0.0673 and 0.1628, respectively. An unusual structural feature of the compound is that the polyanion [Cu4(H2O)2(AsW9O34 )2]10- is linked with the amino acid complex of Cu 2+ by a μ-oxygen atom.
