| Resumo |
Four kinds of new molybdotungstoniobic diphosphates with the Dawson structure, formulated as alpha-P2W15Mo2Nb62(7-), are prepared and characterized by IR, UV spectra, polarography and W-183 NMR which show that the same ''polar'' W atoms in the Dawson frames-are substituted. The mean value of W-183 chemical shifts of the ''polar'' group varies linearly with the number of substituted atoms in the opposite polar group. |
