The Ti₇-Containing, Tetrahedral 36-Tungsto-4-Arsenate(III)[Ti₆(TiO₆)(AsW₉O₃₃)₄]^20-

We have prepared the Ti₇-containing, tetrahedral 36-tungsto-4-arsenate(III) [Ti₆(TiO₆)(AsW₉O₃₃)₄]^20- (1) in a simple, one pot procedure. Polyanion 1 contains a novel Ti₇-core, comprising a central TiO₆ octahedron surrounded by six TiO₅ square-pyramids, capped by four {As^IIIW₉} trilacunary fragments. The title polyanion is solution-stable, as shown by ¹⁸³W NMR and mass spectrometry, and exhibits interesting biological properties.
