Abstract

The first examples of a pentacarbonylzirconium complex, [Zr(CO)5(SnMe3)2]2- and an arylphosphine substituted zirconium(0) species, [Zr(CO)4(dppe)SnMe3]- were obtained by the reaction of [Zr(η4-naphthalene)3]2- with Me3SnCl followed by carbonylation in the absence or presence of dppe, respectively. Both compounds were structurally characterized and represent the initial organotin derivatives of Zr(0). Solutions of [Zr(CO)5(SnMe3)2]2- decompose within hours in CH3CN at 20°C to provide an especially robust formally divalent zirconium complex, [Zr(CO)4(SnMe3)4]2- containing eight coordinate zirconium. The latter has been unambiguously characterized by IR, 13C and 119Sn NMR spectra.
