“…In addition this spectrum shows two wellseparated bands at higher energy (1089 and 1038 cm -1 ) attributed to the {P=O} vibrators. The splitting of the ν P-O stretching mode is comparable to the one observed in the free lacunary [α-PW 11 O 39 ] 7-anion (∆ν ≈ 45 cm -1 ), in agreement with the absence of interaction of Ru addenda atoms with the oxygen atoms of the {PO 4 } group. Cyclic voltammetry of Rb 9.5 K 0.5 -1 at pH = 3 in a sulfate buffer reveals the presence of a reduction wave at E 1/2 = -0.02 V and an oxidation wave at +0.65 V vs. SCE (Figure 4).…”

“…This chemical shift is, however, unusual for diamagnetic ruthenium-, and more generally for diamagnetic metallic-containing derivatives of the [PW 11 O 39 ] 7-anion. Nevertheless, it is noteworthy that a similar value(δ = +0.2 ppm) was observed for the signal arising from the phosphorus atoms closer to the Ru-O-Ru bridge in the related [{α 2 …”

“…[16] The 183 W NMR spectrum of the Li + salt of 1 recorded at 333 K for solubility reasons (Figure 2) displays six major [15,21,32] Nevertheless it is difficult to compare these complexes since i) the number of d electrons of the ruthenium is different in all these complexes, and ii) in the title compound, Ru-O-W angles are higher than in the [PW 11 O 39 {RuL}] n-species, due to the specific linking of the Ru atoms in 1. [70] Nevertheless, these data also confirm the oxidation state +IV in 1, since {Ru III -O-Ru III } bridges are usually characterized by a band at lower energy (in the range 580-670 nm) assigned to a RuǟO 2-charge transfer transition.…”

“…More generally, this complex is the second example of a Ru IV derivative of the [α-PW 11 O 39 ] 7-anion. We thus have shown that it has been possible to obtain a new complex, which is different from the [PW 11 O 39 {Ru…”

The high‐valent ruthenium‐containing [{PW11O39}2{(HO)RuIV–O–RuIV(OH)}]10– anion (1) has been synthesized by hydrothermal reaction and characterized by X‐ray diffraction, IR, multinuclear (31P and 183W) NMR spectroscopy andelectrochemistry. Single‐crystal analysis was carried outon Rb10[{PW11O39}2{(HO)RuIV–O–RuIV(OH)}]·21H2O, which crystallizes in the monoclinic system, space group P21/n, with a = 11.1912(14), b = 21.9257(12), c = 38.7310(96) Å, β = 94.682(19)°, V = 9472(3) Å3, Z = 4. Polyanion 1 consists of two lacunary [α‐PW11O39]7– anions connected by a linear {(HO)Ru–O–Ru(OH)}4+ unit. Each ruthenium ion achieves six‐coordination through interaction with two terminal oxo ligands from the lacuna of each [PW11O39]7– anion.(© Wiley‐VCH Verlag GmbH & Co.
