摘要：

The syntheses of the W = W triply bonded species [W2(eta-C5H4R)2X4] (X = Cl, R = Me or Pr(i); X = Br, R = Pr(i) and of their singly bonded congeners [Mo2(eta-C5H4R)2 [Mo2(eta-C5H4R)2(mu-X)4] (X = Cl, R = Me or Pr(i); X = Br, R = Me) are reported along with X-ray crystal-structure determinations of [W(eta-C5H4Pr(i))Cl4] and [W2(eta-C5H4Pr(i)2Cl4]. The molecular structure of [W2(eta-C5H4Pr(i)2Cl4] consists of two mutually trans W(eta-C5H4Pr(i))Cl2 units linked by an unsupported W = W triple bond [W = W 2.367 8(6) angstrom].
