A vibrational study of the diosmacyclobutene complex Os2(CO)8(μ2–η1,η1–C2H2): The use of organometallic complexes as vibrational models for chemisorbed ethyne
Abstract
The vibrational frequencies of the diosmacyclobutene ring in Os2(CO)8(μ2–η1,η1–C2H2)
(1) and its dideuterated isotopologue Os2(CO)8(μ2–η1,η1–C2D2)
(1-d2) have been measured and assigned. A normal coordinate analysis shows that the CC bond is weakened relative to those in
