U. Lee

Abstract: The [H₃PtW₆O₂₄]^5- anion has close to m symmetry, with Pt-O bond lengths in the range 1.97  (1)-2.01  (1)  Å and W-O bond lengths in the ranges 1.72  (1)-1.78  (1)  (O_t), 1.91  (1)-1.96  (1)  (O_b) and 2.14  (1)-2.33  (1)  Å (O_c), where O_t are terminal atoms, O_b bridge two W atoms, and O_c triply bridge one Pt and two W atoms. The protonated O atoms participate in strong interanion hydrogen bonds.
