and Co–Zn heteronuclear carbonyl cation complexes are produced
via a laser vaporization supersonic cluster source in the gas phase.
The dinuclear FeZn(CO)5+ and CoZn(CO)7+ cation complexes are observed to be the most intense
heterodinuclear carbonyl cation species in the mass spectra. The infrared
spectra are obtained via mass selection and infrared photodissociation
spectroscopy in the carbonyl stretching frequency region. Their geometric
and electronic structures are assigned with the support of density
functional calculations. The FeZn(CO)5+ complex
is determined to have a (OC)5Fe–Zn structure with
a Fe–Zn half bond. The CoZn(CO)7+ ion
is established to have a staggered (OC)4Co–Zn(CO)3 structure involving a Co–Zn σ single bond.
