Crystal structure of hexakis(μ2-4-tert-butoxy-4-oxobut-2-en-2-olato)trizinc

Abstract

The title complex, systematic name hexakis(μ2-4-tert-butoxy-4-oxobut-2-en-2-olato)-1:2κ9O2,O4:O2;2:3κ9O2,O4:O2-trizinc, [Zn3(C8H13O3)6], synthesized from tert-butyl acetoacetate and diethylzinc, consists of trinuclear centrosymmetric molecules of an approximate C3i symmetry. The three metal cations are arranged in a linear fashion, with the central ZnII atom located on a centre of symmetry. All three metal cations exhibit a distorted octahedral coordination geometry. The terminal ZnII cations are chelated by three tert-butyl acetoacetate ligands and these units are connected to the central ZnII atom by the bridging enolate O atoms.
