Vibrational studies of the cluster carbonyls of ruthenium and osmium. Part 1. Raman solution data for [Ru3(CO)12], [Os3(CO)12], and [Ru4H4(CO)12] in the CO stretching region

Abstract

Hitherto unobtainable Raman solution data for [Ru₃(CO)₁₂], [Os₃(CO)₁₂], and [Ru₄H₄(CO)₁₂] in the carbonyl stretching region are presented. The results were obtained by careful choice of solvent and specialist instrumentation. They are shown to confirm previous assignments, by examining the special vibrational properties of cluster compounds. Preliminary results for [Ru₅C(CO)₁₅] are also given.
