Abstract:
|
The 9-cobalt(II)-containing trimeric, cyclic polyanion [Co9(OH)3(H2O)6(PO4)2(B-α-GeW9O34)3]21− (1) was synthesized in an aqueous phosphate solution at pH 8 and
isolated as a hydrated mixed sodium−cesium salt. Polyanion 1
was structurally and compositionally characterized in the solid
state by single-crystal X-ray diffraction, Fourier transform
infrared spectroscopy, as well as thermogravimetric and
elemental analyses. The magnetic and electrochemical proper-
ties of 1 were also studied and compared with those of its
phosphorus analogue, [Co9(OH)3(H2O)6(HPO4)2(B-α-
PW9O34)3]16− (Co9-P). The electrochemical water oxidation
activity of the cesium salt of 1 under heterogeneous conditions
was also studied and shown to be superior to that of Co9-P. The experimental results were supported by computational studies. |
