    • Synthesis of 1: in a 10 mL beaker, 2.520 g (4.5 × 10 -4 mol) of Na14[As2W19O 67]·H2O, 0.147 g (4.5 · 10-4 mol) of Na2WO4· 2H2O, and 0.076 g (4.5 × 10-4 mol) of Mn(SO4) are dissolved in 5 mL of water at T, 70, 80°C. The pH of the mixture is adjusted to 2.2 with 1 M HCl, and the red solution is stirred for 15 min. After cooling to room temperature, 3 g (2.2 × 10-2 mol) of RbCl is added, and a few minutes later, the resulting orange precipitate is filtered and washed with 1 M KCl and dried with ethanol and ether. Yield: 2.1 g (85, A total of 0.7 g of the powder are then recrystallized in 5 mL of water with gentle heating. After 1 night, 0.210 g of orange parallelepipedic crystals of 1 suitable for X-ray diffraction are obtained. IR νmax/cm-1, 963s, 913sh
