The static and dynamic stereochemistry of cis-bis(eta(4)-1,3-butadiene)dicarbonyl-molybdenum(0)(1) and -tungsten(0)(2), as well as of cis-dicarbonyl-bis(eta(4)-1,3-cyclodexadiene)chromium(0)(3), -molybdenum(0)(4) and -tungsten(0)(5) was studied by IR and NMR spectroscopy. The complexes 1-5 show temperature-dependent NMR spectra, according to hindered ligand movements. In the case of 1, the crystal and molecular structure were determined by an X-ray diffraction analysis.
