P.A. Abramov, C. Vicent, N.B. Kompankov, A.L. Gushchin, M.N. Sokolov «Platinum polyoxoniobates» Chem. Commun., 2015, 51, 4021–4023 DOI: 10.1039/C5CC00315F

Reaction of K7H[Nb6O19]·13H2O with [Pt(OH)4(H2O)2] upon heating gives first platinum polyniobates. A dimeric complex [Nb6O19{Pt(OH)2}]212– (1) is produced if the reagents are taken in 1:1 molar ratio. It was isolated and structurally characterized as Cs2K10[Nb6O19{Pt(OH)2}]2·13H2O (Cs2K10-1). Increasing the Pt/Nb6 ratio to 1:2 yields a mixture of 1 and sandwich-type [(Nb6O19)2Pt]12– (2) which was isolated and structurally characterized as Na2K10[(Nb6O19)2Pt]·18H2O (Na2K10-2).
