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

The title complex, systematic name hexakis(mu(2)-4-tert-butoxy-4-oxobut-2-en-2-olato)-1: 3 kappa(9) O-2, O-4 : O2; 2: 3 kappa(9) O-2, O-4 : O-2-trizinc, [Zn-3(C8H13O3)(6)], synthesized from tert-butyl acetoacetate and diethylzinc, consists of trinuclear centrosymmetric molecules 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 octahedral coordination geometry. The terminal Zn-II cations are chelated by three tertbutyl acetoacetate ligands and these units are connected to the central Zn-II atom by the bridging enolate O atoms.
