摘要：

Mild pyrolysis of arachno-(Cp*RuCO)(2)B2H6, 1 (Cp* = eta(5)-C5Me5), with Fe-2(CO)(9) leads to the isolation of a mixed-metal tetrahedral cluster, [Cp*Ru(CO)(2)(mu-H){RuFe3(CO)(9)}], 2, in which [Cp*RuH(CO)(2)] is attached to the tetrahedral cluster in an exopolyhedral manner. Cluster 2 can be viewed as 52-cve (cluster valence electron) tetrahedral cluster, in which the Ru fragment occupies the low connectivity cluster vertexes and participates in an exopolyhedral hydrogen-bridged ruthenium ruthenium double bond. Cluster 2 has been characterized by mass spectrometry, IR, and H-1, B-11, and C-13 NMR spectroscopy, and the geometric structure was unequivocally established by crystallographic analysis.
