Structure and Spectroscopy of Triruthenium Dodecacarbonyl, Ru₃(CO)₁₂.

ABSTRACT: We have reinvestigated the structure and vibrational spectroscopy of triruthenium dodecacarbonyl, Ru₃(CO)₁₂, in the solid state by neutron powder diffraction, inelastic neutron scattering (INS), infrared and Raman spectroscopies. We find that the known room temperature P2₁/n structure is maintained down to 10 K. The unit-cell parameters follow a Debye relationship, with an overall 5.9% volume contraction from 300 to 10 K. The high resolution data at 10 K has enabled the most precise determination of the structure to date. INS spectroscopy, which has no selection rules, has allowed the observation of all the fundamentals below 700 cm^-1 for the first time. In combination with new low temperature infrared and Raman spectra, this has re
