| Abstract: | | 1. | Perfluoro-tert-butanol forms H bonds of the OH...OC-M type with transition metal carbonyl  complexes: CpM(CO)3 (Cp= 5-C5H5 and 5-Et5C5, M=Mn, Re), MezM(CO)3 (Mez = 6-Me3H3C6, M=Cr, Mo, W), (5-C5H5)M(CO)2PR3 (R=Ph, i-Pr, M=Mn, Re) at low temperatures in liquid xenon and at  20 C in CCl4. | | 2. | For isostructural complexes, the basicity of the O atom of the CO group increases on substitution of one of the CO groups by a phosphine ligand, introduction of alkyl substituents in the ring, and in going from Mn to Re. | | 3. | Hexacarbonyls M(CO)6 (M=Cr, Mo, W) do not form an H bond with perfluro-tert-butanol. |
