Decamethyldizincocene (Zn-2(eta(5)-Cp*)(2)) is the first example of a stable organometallic compound with a homonuclear metal Zn-Zn bond. Although its structural properties have been characterized by X-ray diffraction and high-resolution mass spectroscopy, it has been suggested that its experimental infrared and Raman spectra might not be particularly useful in identifying the Zn-Zn stretch mode in Zn-2(eta(5)-Cp*)(2), We have used density-functional theory (DFT) to calculate both an infrared (IR) and Raman spectra for Zn-2(eta(5)-CP*)(2). In particular, our results clearly identify a number of low frequency Raman active modes wherein Zn-Zn twist and stretch modes are clearly identifiable. Published by Elsevier B.V.
