The tris(phenyltin)-substituted tungstoantimonate(III) Cs6[(PhSn)3Na3(α-SbW9O33)2]·20H2O (1) and the tetrakis(phenyltin)-substituted tungstoarsenate(III) Na9[{(PhSn)2O}2H(α-AsW9O33)2]·20H2O (2) have been prepared by reaction of phenyltin trichloride with Na9[α-SbW9O33]·19.5H2O and Na9[α-AsW9O33]·19.5H2O, respectively, in aqueous solution. The products were characterized by elemental analysis, X-ray crystallography, multinuclear NMR, and infrared spectroscopy. Crystals of 1 are monoclinic, space group P21/n, with a = 13.7952(1) Å, b = 22.3133(2) Å, c = 34.4493(2) Å, β = 90.933(1)°, and Z = 4. Anion 1 has nominal D3h symmetry and contains three PhSn3+ groups and three sodium ions sandwiched between [α-SbW9O33]9- units. Crystals of 2 are triclinic, space group P1̄, with a = 15.272(6) Å, b = 15.303(6) Å, c = 16.760(7) Å, α = 93.59(3)°, β = 106.187(19)°, γ = 112.23(3)°, and Z = 1. Anion 2 has nominal C2h symmetry and contains four PhSn3+ groups sandwiched between two [α-AsW9O33]9- units.
