The Ru(ii)-supported heptatungstates [HXW7O28Ru(dmso)3]6− (X = P, As)†
Abstract
The ruthenium(II)-supported heteropolyanions [HXW7O28Ru(dmso)3]6−
(X = P, 1; As, 2) are composed of a Ru(dmso)3 group attached to an unprecedented heptatungstate fragment via two Ru–O–W bonds and one Ru–O–X bond, which represents a fundamentally novel mode of Ru-coordination to a polyoxoanion framework. Multinuclear 183W, 31P, 13C, and
