title: Crystal structure of hexa-kis-(μ2-4-tert-but-oxy-4-oxobut-2-en-2-olato)trizinc.
abstract: The title complex, systematic name hexa-kis-(μ2-4-tert-but-oxy-4-oxobut-2-en-2-olato)-1:2κ(9) O (2),O (4):O (2);2:3κ(9) O (2),O (4):O (2)-trizinc, [Zn3(C8H13O3)6], syn-the-sized from tert-butyl aceto-acetate and di-ethyl-zinc, consists of trinuclear centrosymmetric mol-ecules of an approximate C 3i symmetry. The three metal cations are arranged in a linear fashion, with the central Zn(II) atom located on a centre of symmetry. All three metal cations exhibit a distorted octa-hedral coordination geometry. The terminal Zn(II) cations are chelated by three tert-butyl aceto-acetate ligands and these units are connected to the central Zn(II) atom by the bridging enolate O atoms.
