Reaction of the ammonium salt of keplerate, [{(MoVI)MoVI5O21(H2O)6}12{MoV2O4CH3COO)}30]42– with Gd(NO3)3 leads to complex transformations with [{Gd(H2O)5}4{Mo36(NO)4O108(H2O)16}]·34 H2O (1) as final product. According to X-ray structural data it contains anions [Mo36(NO)4O108(H2O)16]12–, cross-linked into a neutral 2D-framework by Gd3+ ions. To cite this article: N.V. Izarova et al., C. R.

RésuméLa réaction entre le keplerate d'ammonium [{(MoVI)MoVI5O21(H2O)6}12{MoV2O4CH3COO)}30]42– et le nitrate de gadolinium Gd(NO3)3 conduit à des transformations complexes, dont la résultante ultime est le composé [{Gd(OH2)5}4{Mo36(NO)4O108(OH2)16}]·34 H2O (1). L'analyse structurale par diffraction des rayons X montre un réseau bidimensionnel construit à partir du fragment polyoxométallique {Mo36(NO)4O108(OH2)16}, interconnecté par les groupes {Gd(OH2)5}.
