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.
该配合物的系统名称为hexa-kis-(μ2-4-叔丁基-氧-4-氧丁基-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]，由乙酸叔丁基和二乙基锌合成，具有近似c3i对称的三核中心对称分子。这三个金属阳离子以线性方式排列，中心的Zn(II)原子位于对称中心。这三种金属阳离子都表现出扭曲的八面体配位几何。末端的Zn(II)阳离子被三个叔丁基乙酰乙酸配体螯合，这些单元通过桥接烯醇酸O原子连接到中心的Zn(II)原子上。
期刊介绍：
Acta Crystallographica Section E: Structure Reports Online is the IUCr highly popular open-access structural journal. It provides a simple and easily accessible publication mechanism for the growing number of inorganic, metal-organic and organic crystal structure determinations. The electronic submission, validation, refereeing and publication facilities of the journal ensure very rapid and high-quality publication, whilst key indicators and validation reports provide measures of structural reliability. In 2009, the journal published over 4000 structures. The average publication time is less than one month.
