Several heteropolyanion structures accommodate central octahedral heteroatoms an especially widespread type is the Dm Anderson structure (Figure 11 and Table 2). Note that two versions of the structure are known with or without protonation of the central XOe octahedron, depending upon the oxidation state of X. Although the heptametalate anions, [M7O24] (Figure 5), can be considered to be Ci, isomers of the Anderson anions, few heteropolyanions have so far been shown to adopt the former structure. 

Bi-capped versions of the Anderson structure are found with [(As C C MogO )]4-307 and [HxXMo6Oi8 RC(CH20)3 2](6 m x) (Xm 1 Fe31, Ni2+, Zn2+).308 The arsenite complex was isolated from a reaction between Co(H20)62+ and [Asin3Mo30i5]3, an anion that was probably first reported in the nineteenth century. The structure of the latter and its tungstate analogue, of... 

The particle sizes were calculated using the Scherrer equation in the form t = O.89X/cos0/(w - w ) where 0 is the Bragg angle, w the half-width of the measured reflection and Wq the instrumental half-width in radians, cf. J. R. Anderson, "Structure of Metallic Catalysts," AP 1975, p 366.

In the present study a well defined inorganic cluster, hexamolybdoplatinate(IV) heteropolyanion, was employed as a bimetal ensemble precursor, which has a plane Anderson structure. The [PtMoej/MgO catalyst prepared by supporting the hexamolybdoplatinate(IV) heteropliyanion on MgO, followed by calculation at 773K, showed a unique surface structure and better catalytic performance for the alkane-to-alkene conversion than a conventional coimpregnation catalyst.[15]...
