Bottom Line: 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.

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.

fig2: The crystal packing of the title compound, in a projection along the b axis. H atoms have been omitted for clarity.

Mentions: There are no short inter­molecular contacts between neighbouring mol­ecules in the crystal. The mol­ecules are closely packed into (01) layers (Fig. 2 ▶). The mol­ecules within the layers are arranged so that their tert-butyl ends are directed towards the central parts of neighbouring mol­ecules (Fig. 3 ▶).
