The reaction of [Na(tmeda)][2] with BaI2 resulted in the formation of [Ba(thf)5(μ-η7:η7-C7H7)Zr(η5-C2B9H11)][(η7-C7H7)Zr(η5-C2B9H11)], [Ba(thf)5(2)][2], in which the cation exhibits an unusual bridging μ-η7:η7-C7H7 unit between the Dcb-Zr and the Ba(thf)5 fragments. An analogous reaction could not be effected by the salt metathesis reaction between [Na(tmeda)][2] and 0.25 equivalents of [(η5-C5Me5)Ru(μ3-Cl)]4
