Abstract
The structure of the fully protonated hexamolybdoplatinate polyanion salt K 2 [H 6 α-PtMo 6 O 24 ] . 5H 2 O has been determined from X-ray diffraction data. This polyanion has a center of symmetry and protonation of the O atoms is different from that of heteropolyanions having the socalled Anderson structure, [X n+ (OH) 6 Mo 6 O 18 ] (6−n)− (X is a hetero atom), where all the 0 atoms in the central XO 6 octahedron are protonated. In the present compound, four central (Pt−Oc−Mo2) and two bridging (Mo− Ob−Mo) O atoms are protonated
