Abstract
The ion-exchange between the transition metal monosubstituted heteropo lyoxometalate anion [SiW11O39Co(H2O)](6-) and the anionic clay Zn2Al(O H)(6)NO3 . xH(2)O by the action of ultrasound gave the heteropolyanion -pillared layered double hydroxide Zn2Al(OH)(6)[SiW11O39Co(H2O)](1/6). 4H(2)O within 7 min. The product was characterized by powder X-ray di ffraction, i.r. spectroscopy and elemental analysis. The results show that the gallery height of the complex is 1.00 +/- 0.02 nm and the het eropolyanion [SiW11O39Co(H2O)](6-) entering the layer retains the inte grity of the Keggin structure. Experimentally, the atomic ratio of eac h element in the formula is Zn:Al = 2.1:0.95 and Si:W:Co = 0.96:10.90: 0.98.
