摘要：

Mild thermolysis of (η-C5Me5)(CO)Ni–M(CO)3-(η-C5H5) (M = Mo, W) afforded the paramagnetic coordinatively unsaturated species (η-C5Me5)Ni–M(CO)3(η-C5H5). Irreversible decarbonylation to the tetrahedral clusters Ni2M2(CO)4(η-C5H5)2(η-C5Me5)2 occurred on prolonged heating. The compound (η-C5Me5)Ni–W(CO)3(η-C5H4Me) was characterized by an X-ray diffraction study: short nickel–tungsten distances of 2.475 (2) and 2.457 (2) Å for the two independent molecules in the unit cell indicate multiple Ni–W bond character. © 1990, American Chemical Society.
