摘要

(C_5H_7N_2)_3(AsMo _(12)O_(40)). 2C_5H_6N_2. 1.5H_2O was hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. Crystal data: monoclinic, P2_1, a = 13.310(3), b = 22.399(5), c = 19.820(4) ?, β = 99.99(3)°, V = 5819(2) ?~3, Z = 1, wR(F~2) = 0.1345. The structure consists of Keggin-type [AsMo_(12)O_(40)]~(3-) polyoxoanions. The title compound has a high catalytic activity for the oxidation of acetone tested in a continuous-flow fixed-bed micro-reactor. When the initial concentration is 5.3 g m~(-3) in air and the flow rate is 2.5 mL min~(-1), the acetone is completely eliminated at 150 °C.
