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.
