The 4-picolinium salt (C6H8N)3[PMo12O40] was synthesized hydrothermally and characterized by IR spectroscopy, TG-DTA data and single-crystal X-ray diffraction. The results indicate that the compound consists of a [PMo12O40]3− heteropolyoxoanion and 4-picolinium cations [C6H8N]+. A supramolecular structure is formed via intermolecular hydrogen-bonding between the different structural units. Crystal data: monoclinic, space group P21/c, a = 19.7004(3), b = 14.0785(2), c = 33.0209(5) Å, β = 91.3590(10)°, V = 9155.8(2) Å3, Z = 8, wR2 = 0.0730. (C6H8N)3[PMo12O40] has a high catalytic activity for the oxidative elimination of acetone from gases as tested in a continuousflow fixed-bed micro-reactor. When the initial concentration is 5.2 gm−3 in air, and the flow rate is 3.3 mLmin−1, 93% of the acetone is eliminated at 70 °C.
