At variance with what was previously reported, Mn2(CO)10 does not transform its conformation from staggered to eclipsed in the high pressure crystal form. X-ray powder diffraction, DFT calculations and Raman spectroscopy show that the staggered conformation is retained. Instead, a rotation and a translation of the Mn(CO)5 pyramidal units produce an ‘‘off-axis’’ and rather shorter Mn–Mn bond.
