Abstract:
The formation of bimetallic Pd(II) and M = Fe(III), Ti(IV), V(V), Co(II), or Cu(II) complexes with the two-vacancy [As2W19O67(H2O)]14– heteropolyanion (HPA) (below referred to as As2W19) has been studied by UV/Vis and IR spectroscopy and differential dissolution. In an aqueous solution at pH 6 and a Pd : M : As2W19 molar ratio of 1 : 1 : 1, heteropoly complexes (HPC) incorporating two different metals one being Pd(II) are formed. The resulting complexes were precipitated from solution as cesium salts. In the case of Pd(II) and M = Fe(III), Co(II), or Cu(II) ions, the precipitate contained bimetallic HPC [As2W19FePdO67(H2O)2] 9– (65.9 wt %), [As2W19CoPdO67(H2O)2]
10– (45.6 wt %), and [As2W19CuPdO67(H2O)2] 10– (50.7 wt %) mixed with monometallic HPC [As2W19M2O67(H2O)2]
(14 – 2m)– (As2W19M2). In the case of Pd(II) and Ti(IV) or V(V), bimetallic HPC of a different composition were precipitated, namely, [As2W19Ti2O67(OHx)2 PdO] (10 – 2x)– (76.8 wt %) and [As2W19V2O67(OHx)2 PdO]
(8 – 2x)– (15.0 wt %), where palladium ions are not incorporated in the HPC structure but are attached to the HPC surface, possibly, as hydroxide species. Using M = Pd(II), Ti(IV), V(V) ions and the HPA As2W19 ([M] : [As2W19] = 2 : 1, ç 6), new monometallic HPC, [As2W19Pd2O67(H2O)2]10–, [As2W19Ti2O67(OHx)2](10 – 2x)–, and [As2W19V2O67(OHx)2] (8 – 2x)– (x = 0, 1, or 2), were obtained.
