A new polyoxotungstate (NH4)(7)[Bi(H2W12O42)] (.) 20H(2)O has been synthesized in aqueous solution and characterized by elemental analysis, IR spectroscopy, TG analysis and single-crystal X-ray diffraction. The most interesting structural feature of 1 is that the paradodecatungstate [H2W12O42](10-) anions are linked, for the first time, by the trivalent main group atom Bi-III which appeared commonly as a heteroatom in polyoxometalate chemistry, into a one-dimensional chainlike structure.
