- Аннотация: Carbonyl perchlorates [M(ClO4)(CO)5] (M ¼ Tc, Re) were prepared by treatment of [TcI(CO)5] and[ReCl(CO)5], respectively, with AgClO4 in dichloromethane. The complexes were isolated in the form ofyellowish and colorless crystals, respectively, and characterized by IR spectroscopy and single crystal Xray diffraction (XRD). Perchlorate ion is coordinated to the central atom in the monodentate fashion.Perchlorate ligand in the coordination sphere of [M(ClO4)(CO)5] (M¼ Tc, Re) can be readily substituted by a molecule of a coordinating solvent (acetonitrile). [Re(CO)5(CH3CN)]ClO4 is stable with respect tothermal decarbonylation and was isolated and characterized by single crystal XRD. The coordinationpolyhedron of rhenium in [Re(CO)5(CH3CN)]ClO4 is less distorted than that in [M(ClO4)(CO)5].[Tc(CO)5(CH3CN)]ClO4, contrary to its rhenium analog, is unstable in acetonitrile solution and undergoes rapid decarbonylation to form [Tc(CO)3(CH3CN)3]ClO4.
