The mass spectra of some polynuclear cobalt carbonyl compounds: a suggested structure for hydridododecacarbonylirontricobalt and hydridododecarbonylrutheniumtricobalt

Abstract

The mass spectra of a series of compounds XCCo₃(CO)₉ have been investigated. The spectrum of PhCCo₃(CO)₉ is described in detail, as representative of the series. The mass spectra of HFeCo₃(CO)₁₂ and HRuCo₃(CO)₁₂ are reported. On the basis of the mass spectroscopic and infrared results, a structure is proposed for these two complexes in which the hydrogen atom is located inside the metal-atom cage.
