Abstract

Zigzag bridge: The allylcalcium monocation was found in the solid-state structure of [Ca(μ2-η1:η1-C3H5)([18]crown-6)]+[Zn(η1-C3H5)3]−. This allyl ligand exhibits an unusual bridging mode within a hexagonal-bipyramidal non-bent coordination geometry (see picture: Ca green, Zn blue, O red, C gray).
