THE NONASODIUM SALT OF THE TRINIOBIUM-SUBSTITUTED POLYOXOANION P2W15NB3O62(9-) - A WATER-SOLUBLE, READILY CRYSTALLIZED FORM OF THIS DAWSON-BASED SOLUBLE METAL-OXIDE ORGANOMETALLICS-SUPPORT SYSTEM
K. Nomiya et al., THE NONASODIUM SALT OF THE TRINIOBIUM-SUBSTITUTED POLYOXOANION P2W15NB3O62(9-) - A WATER-SOLUBLE, READILY CRYSTALLIZED FORM OF THIS DAWSON-BASED SOLUBLE METAL-OXIDE ORGANOMETALLICS-SUPPORT SYSTEM, Inorganic chemistry, 33(7), 1994, pp. 1469-1472
The preparation of the Dawson-type heteropolyoxoanion P2W15Nb3O629- as
its water-soluble sodium salt, Na9P2W15Nb3O62.23H2O, is described. Th
e title compound is obtained on up to a 13-g scale as an analytically
pure, homogeneous white solid in 61% yield. It was characterized by a
complete elemental analysis, TG/DTA, IR spectroscopy, and multinuclear
P-31 and W-183 NMR spectroscopy.
