A novel manganese(IV)-containing symmetrical heteropolyvanadate was prepared by the transformation of K₇[MnV₁₃O₃₈]路18H₂O (K₇MnV₁₃) to K₄Li₂[MnV₁₄O₄₀]路21H₂O (1) at pH 4. The heteropolyanion [MnV₁₄O₄₀]p>6鈥?/sup> (MnV₁₄) is composed of a MnO₆ octahedron surrounded by 14 edge-sharing VO₆ octahedra. The simplified representation of MnV₁₄ has a new topology termed jba1 with a total point symbol of {3p>10p>}2{3p>14p>.4p>7p>}4{3p>18p>.4p>10p>}8{3p>44p>.4p>46p>.5}. In the crystal lattice of 1, MnV₁₄ packs with potassium ions, forming a 2D layered K₂[MnV₁₄O₄₀]p>4鈥?/sup> network (ABABAB...). Four Kp>+p> ions cap the four square O₄ faces of MnV₁₄, apparently stabilizing the heteropolyanion. Compound 1 catalyzes the t-BuOOH-based oxidation of 2-chloroethyl ethyl sulfide (a mustard gas simulant). The magnetic and catalytic properties of 1 are discussed.
