The novel Ti2-containing, sandwich-type 18-tungsto-2-arsenate(III) [(TiIVO)2(伪-AsIIIW9O33)2]14鈥?/sup> (1) was successfully synthesized by the reaction of [TiO]2+ species with [伪-AsIIIW9O33]9鈥?/sup>. The monolacunary polyanion 1 is solution-stable, and a further reaction with 1 equiv of phenylantimony(III) dichloride resulted in [C6H5SbIII(TiIVO)2(伪-AsIIIW9O33)2]12鈥?/sup> (2). Both polyanions 1 and 2 were structurally characterized in the solid state and solution. Electrochemical studies were also performed on both polyanions.
