Abstract
AbstractThe 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.
