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 1H NMR studies indicate high stability of 1 and 2 in solution.
