N2 - We report the first Peacock–Weakley type complexes composed of mono-lacunary Keggin-type phosphotungstate, [α-PW11O39]7–, and Bi3+. The self-assembly reaction between the Keggin-type phosphotungstate and Bi3+ in aqueous solution produced Peacock–Weakley type 2:1 ([(PW11O39)2Bi]11–, 1) and 1:1 ([PW11O39Bi]4–, 2) complexes depending on the mixing ratio of [α-PW11O39]7– and Bi3+. Studies of both complexes in solution were conducted by different NMR techniques including 31P and 183W analyses. Complex 1 was successfully isolated as both tetramethyl ammonium (1a) and potassium (1b) salt, and characterized by single-crystal X-ray diffraction, IR spectroscopy and elemental analysis. The sandwich structure of 1a and 1b was determined to be constructed by eight Bi–O bonds with two [α-PW11O39]7– units.
