Inorganic compounds containing the trifluoroacetate group. Part I. Pentacarbonyl(trifluoroacetato)manganese and substituted derivatives

Abstract

Physical properties of pentacarbonyl(trifluoroacetato)manganese have been investigated. Discrepancies in i.r. spectra reported in earlier studies have been resolved and new data, including Raman, ¹⁹F n.m.r., X-ray photoelectron, and mass spectra, and molecular-weight measurements, have been obtained. A convenient route to substituted derivatives of this compound has been developed and the new compounds [Mn(CO)₃L₂(O₂CCF₃)][L = pyridine (py) or PPh₃; L₂= 2,2′-bipyridine (bipy), 1, 10-phenanthroline (phen), RSCH₂CH₂SR (R = Et or Ph)] isolated and characterised.
