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

The title complex, systematic name hexa­kis­(μ(2)-4-tert-but­oxy-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, [Zn(3)(C(8)H(13)O(3))(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 tert-butyl aceto­acetate ligands and these units are connected to the central Zn(II) atom by the bridging enolate O atoms.
