Abstract
The syntheses of the WW triply bonded species [W2(η-C5H4R)2X4](X = Cl, R = Me or Pri; X = Br, R = Pri) and of their singly bonded congeners [Mo2(η-C5H4R)2(µ-X)4](X = Cl, R = Me or Pri; X = Br, R = Me) are reported along with X-ray crystal-structure determinations of [W(η-C5H4Pri)Cl4] and [W2(η-C5H4Pri)2Cl4]. The molecular structure of [W2(η-C5H4Pri)2Cl4] consists of two mutually trans W(η-C5H4Pri)Cl2 units linked by an unsupported WW triple bond [WW 2.367 8(6)Å].Keywords
